Cleanups:

 * dropped needless definition of aibcc_enabled
 * renamed master_partition_monitor_monitor_httpd_port to
   MASTER_PARTITION_MONITOR_HTTPD_PORT
 * convert buildout comments to Jinja2 comments
 * strip whitespaces, so that generated file is readable
 * correctly indent on Jinja2 not on buildout
 * drop obvious comments
 * minimize amount of variables, by dropping used only once
 * pass all modules with _module suffix
 * avoid passing needless software_type
 * group definition of all globals into one place
 * name all globals with UPPERCASE

XXX: Clean up until it will be possible to modify it a lot

Change how defaults are handled in the cluster:

 * master instance handles all defaults for all nodes
   * it is the one place with all defaults
   * depending on parameter style default is global for the cluster or can be
     specified per node with -frontend-config-<i>-parameter
 * kedifa and frontend nodes need everything to be passed, in order to
   simplify the request
 * configuration. defaults are dropped, as their scope is too large - they are
   not only defaulting the value on the master, but on each requested node
   which leads to extreme complexity of parameter passing
 * use extra_slave_instance_list only, as instance-slave-list is reserved
   parameter provided by slapos.cookbook:slapconfiguration, sent by SlapOS
   Master as slave_instance_list, to the master partition; enforce
   transmissions of slave list in extra_slave_instance_list and consider
   it's always present
 * useless replication_number return value is dropped

This is required simplification, as the cluster needs full control over
defaults on each level.

Assert `open62541` library works by joining a multicast group.

Update component to be suitable for osie-coupler

1.0.0 was not python2 compatible, setuptools ignored this

See merge request nexedi/slapos!1257

This brings updates of many dependencies on python3, while mostly
keeping the same versions for python2.

This enables a new `erp5-py3` test in software/slapos-sr-testing, which
should pass already, but with NEO and WCFS being marked as expected
failure or skipped for now.

This also brings pylint support on python3, which we will be able to
reuse in software/slapos-testing.

This bring new versions of jupyter, numpy and other scientific python
software. This impacts software/jupyter, which will now run more recent
versions and prepares stack/erp5 for python3 support, while not
impacting the python2 version.

This reverts commit 6c399134.

This is not really specific to python2, it is specific to ERP5, now that
ERP5 uses python3, the naming became not really good

This reverts 1b291415 (component/ghostscript: Workaround for slaprunner
paths with double slashs, 2021-06-02) and 4e9a9cf1 (component/tesseract:
Workaround for slaprunner paths with double slashs, 2021-08-19). We no
longer support slappruner and these commits were causing issues on
python3

statsmodels and websocket-client were pinned to Python3-only versions,
and slapos.toolbox was installed in develop mode from a Python3-only
revision.

fixup ac38a241 (Increase maximum ISO size to 20GB in KVMs., 2024-06-07)

With buildout3 all python2 software must extend this

Some Linux distributions, in particular server distributions such
as RHEL or SLE, have ISOs that are above 10GB in size.
This commits updates the maximum ISO size from 10GB to 20GB, so that
these ISOs can be used when requesting a new KVM.

In 55449aca (software/erp5: describe the allowed formats for family
and frontend names, 2024-01-01) we changed to a stricter definition of
zope and frontends partitions names, but because these objects allowed
additional properties, a partition not matching the pattern would be
anyway be accepted.
