This change the format or the (mostly) unused frontend parameter to
support requesting more than one frontend and also enable the request of
a frontend by default, so that requesting a frontend separately is no
longer needed.

The `frontend` parameter now also supports requesting frontends for
specific paths on the ERP5 backend, the example below requests a
frontend serving directly a web site, with the necessary rewrite rules:

```js
{
  "frontend": {
    "default": {
      "internal-path": "/erp5/web_site_module/renderjs_runner/"
    }
  }
}
```

The example below requests a default frontend to the erp5 root, to
access the ZMI or erp5_xhtml_style interface and two web sites:

```js
{
  "frontend": {
    "default": {},
    "erp5js": {
      "internal-path": "/erp5/web_site_module/renderjs_runner/"
    },
    "crm": {
      "internal-path": "/erp5/web_site_module/erp5_officejs_support_request_ui/"
    }
  }
}
```

The example below has an explicit definition of the zope families using
`zope-partition-dict` parameter, because there is more than one zope
family, no frontend is requested by default:

```js
{
  "zope-partition-dict": {
    "backoffice": {
      "family": "backoffice"
    },
    "web": {
      "family": "web"
    },
    "activities": {
      "family": "activities"
    }
  }
}
```

Continuing this example, to have frontends for backoffice and web
families, the frontend request can specify the families, like it is
demonstrated in the example below. In this example, we don't specify an
entry for "activities" family, so no frontend will be requested for
this family.

```js
{
  "frontend": {
    "backoffice": {
      "zope-family": "backoffice"
    },
    "web": {
      "zope-family": "web",
      "internal-path": "/erp5/web_site_module/web_site/"
    }
  }
  "zope-partition-dict": {
    "backoffice": {
      "family": "backoffice"
    },
    "web": {
      "family": "web"
    },
    "activities": {
      "family": "activities"
    }
  }
}
```

These are already defined in stack/slapos.cfg

jupyter-py2 used an old version not py3 compatible
pygolang/test used the same version as in stack/slapos.cfg

Don't repeat slapparameter_dict['ncell_list'][k] - we can introduce a name for
current neighbour cell, and use that name in the loop. And align entries to
that they read more clearly.

No non-whitespace changes in rendered enb.cfg and gnb.cfg .

We currently have LTE-specific handover configuration in under cell_list and
NR-specific handover configuration in under nr_cell_list. Those configuration
are different.

However in upcoming MultiRU we will need to handle LTE->NR handover, NR->LTE
handover, and also Intra-ENB handover in addition to Inter-ENB handover we
currently do.

-> Move handover code into common function as a preparatory step for that.

In the future the handover code for LTE and NR cells will be the same, so it
makes sense to move that code to common place to avoid duplication.

For rendered enb.cfg this unification introduces only space and trivial
changes as shown in the appendix.

1. Currently we have separate log_options for LTE and NR cases with listing
different subsystems in each. But in MultiRU one enb will be driving both LTE
and NR cells at the same time, so we will need to define both LTE- and
NR-related levels.

-> Merge all log settings into one log_options as a preparatory step

For current state it does not hurt for an LTE if we set e.g. ngap.level, and it
does not hurt for NR if we set e.g. s1ap.level - since those layers will be
unused. This way merging log settings for both LTE and NR subsystems is ok.

--------

2. Factorize log_phy_debug handling: instead of duplicating whole
log_options line and changing only phy.level settings there, construct the
log_options line programmatically and handle phy.level on its own.

--------

3. Use log/enb.log log_filename for both LTE and NR cases. In the upcoming
MultiRU there might be several cells activated at the same time and in general
it will be not possible to say are we doing "enb" or "gnb" now - for example if
there will be two cells - one LTE and one NR.

-> Use enb.log for log filename uniformly similarly to how the software is
named (lteenb) even though it can work as both enb and gnb.

For the reference we do the same with enb.xlog in nexedi/slapos!1522 .

Current enb config is already quite complex and with MultiRU it will be growing
more - both with added features and with more sections emitted because there
will be multiple radio units, multiple cells and cross cell interactions. So
for clarity we will want to annotate with a comment to which cell or ru object
a section belongs, or to which cell-cell pair a particular interaction belongs.

Amarisoft supports C-style comments and preprocessor directives out of the box,
but if we use them in the configuration files, yaml.load, that we use in the
test to load generated configs, will break, because // and /* ... */ is not
valid YAML. It looks like Amarisoft does preprocessing as a separate step
before further loading given configuration via yaml.

So to be able to use the comments and still have tests working we need to do
the same - in the tests preprocess the files before feeding them to yaml loader.

-> Do that with the help of https://pypi.org/project/pcpp/

In my view that library has good quality and in my experience it worked
flawlessly. Anyway we need it to only handle comments, not sophisticated CPP
features, and for that it works just ok.

Add some comments to existing enb.cfg and ue.cfg to make sure it really works.
Those are simple comments, and in current state it they might seem as not 100%
necessary, but with more upcoming config changes it would be good to have those
descriptionary anchors present in the generated configs, so I suggest we add them.
Anyway they should not do any harm at all.

Currently on every test yaml.load issues a warning that using it without
explicitly specifying loader is deprecated, for example:

    test_enb_conf (testTDD.TestENBParameters) .../slapos/software/ors-amarisoft/test/test.py:29: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.

-> Fix the warning by using appropriate loader explicitly.

Use FullLoader since msg.pyyaml.org/load describes it as

   Loads the full YAML language. Avoids arbitrary code execution.
   This is currently (PyYAML 5.1+) the default loader called by yaml.load(input) (after issuing the warning).

i.e. we get support for full YAML feature set, do not get code execution and
make sure that the behaviour stays exactly the same as before, but without the
warning.

We are going to do fixes and enhancements to YAML loading processes. Move
corresponding code to one place before that as the preparatory step.

Place new utility in new test/test.py file - with MultiRU that will be the
place for tests of generic mode and test.jinja2.py, which will be renamed to
test_ors.py, will be using utilities from there. So place the utility into new
place from the start.

In MultiRU one enb will be driving multiple, possible of different kind,
TDD/FDD and LTE/NR cells all at the same time, because that standard
functionality of a base station and because original Amarisoft software
supports that out of the box.

However we currently have enb and gnb services separate and duplicating most of
each other code.

-> Merge instance-enb.jinja2.cfg and instance-gnb.jinja2.cfg as a preparatory step for MultiRU.

- instance-enb.jinja2.cfg pulls gnb specific bits from instance-gnb.jinja2.cfg
- instance-gnb.jinja2.cfg goes away effectively switching gnb to use
  ru/libinstance.jinja2.cfg like enb already does
- For parameters that were duplicated as enb_<X> and gnb_<X>  generic software
  now accepts only enb_<X> with ORS mode wrapper providing backward
  compatibility for gnb_* parameters. For example if gnb_config_link is given
  for a gnb instance, it will be translated to enb_config_link to underlying
  generic enb so that gnb_config_link works correctly.

  For ORS we care to provide 100% backward compatibility because there are many ORS'es deployed.
  For generic software we are free to clean things up as needed, because there
  is not much generic deployments at this time.

In MultiRU we are going to have generic software with flexible configuration
and many features + ORS software, which wraps the generic part, adds ORS
specific features, and translates simple ORS schema to generic ones.

Let's first move ORS-specific bits to dedicated place as a preparatory step for that:

- add software-ors.cfg . In the future software-ors.cfg will be the entry point
  for ORS mode, but for now it is only a place from where software-ors-* extend from.

- add instance-ors.cfg . We move ORS-specific code from instance.cfg here and
  set it to use instance-ors-enb.jinja2.cfg when instantiating enb/gnb.

- add instance-ors-enb.jinja2.cfg . This pulls ORS-specific code from
  instance-enb.jinja2.cfg + instance-gnb.jinja2.cfg and wraps them with ORS
  context built by instance-ors.cfg

- in the templates the way to see whether it is ORS or not, and if yes, to access
  ORS parameters is changed: now it is always via checking `ors` object, which
  can be either False for non-ORS mode, or dict for ORS mode, and if it is dict
  the keys inside that dict are ORS specific properties, e.g. ors['one-watt'].

  This adjustment is handy to organize ORS mode extension from generic with
  generic setting `json ors false` in the context, and ORS mode undoing that and
  setting ORS context properly. I think the code also reads more clear this way, i.e. with

 	{%- if one_watt == "True" %}

  changed to

	{%- if ors['one-watt'] %}

  because in the second variant it is clear that one-watt is a property of ORS.

The rendered configs for enb.cfg and gnb.cfg stay unchanged.

We use computer identifier in fluentd forwarding. This identifier was named as
ors-id, but it applies not only to ORS, but also to generic deployment with
BBU.

In the next patch we are going to introduce ORS mode and move ORS-specific
bits to software-ors.cfg and instance-ors.cfg + co. The computer identifier
will stay in generic part, because it is generic.

-> To avoid ambiguity rename it to be clearly unrelated to ORS specifics.

When there are multiple cells and CA configured, without those parameters enb fails to start with e.g.

    n1_pucch_an_cs_count must be > 0 for the CA Primary cell

Set them on all cell like illustrated in enb-2cc.cfg and enb-3cc.cfg Amarisoft examples.

Not sure selected values are best - I took them from above mentioned examples as is.

Reference to documentation about those parameters:
