This reverts commit 31eaaec1.

This slows down business template by a factor of two and it seems we
don't need it. I'm experimenting with hacks in ppml.py but maybe just
creating the Unpickler with encoding='utf-8' in
product/ERP5Type/XMLExportImport/__init__.py:267 is enough ?

at this point they all fail after long timeouts, because neo does not
support py3 yet

Not sure why it was OK on python2 and not sure if this has to be done
or the promise code needs to cast the results of getConfig()

Otherwise it fails with the following exception because of non-ASCII characters
(`[A-Z&é@{]{3,7})`) (see unconvert()) below):

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 must be installed through dependencies

on python3 we use lzma directly

There are more recent versions, but they don't use pyproject.toml for
metadata.

Here we want a version with python3.11 support

This comes with a patch because the setup.py does not have version,
which is not supported with our old tooling.

This section is just for setup, it does not make sense to generate
scripts here and it cause errors when another section uses the same
technique.

Note that we don't use 3 yet because nexedi/pygolang@6446a0be

In multiRU we will need to be able to check multiple radio units for RX saturation separately.

-> As a preparatory step adjust the SR to explicitly specify the list of RX antennas to be verified.

This patch is necessary because in nexedi/slapos.toolbox!126
we adjust check_rx_saturated plugin to require list of RX channels to check to be
explicitly specified.

In multiRU we will need to be able to check multiple devices and DMA channels,
not only /dev/sdr0@0 that was implicitly used until now.

-> As a preparatory step adjust the SR to explicitly specify which SDR resource is being verified.

This patch is necessary because in nexedi/slapos.toolbox!125
we adjust check_sdr_busy plugin to require SDR device/DMA channel to be
explicitly specified.

also stop enabling pip user installation, this breaks slapos isolation too much

This reverts commit 6f167c36.

This causes issues that unexpectly slapos python processes use user
installed packages. This was to accomodate python extension prompting
user to install packages for them, but current version of the extension
no longer seem to do this.
