* Add an option to avoid signing deb package
* update windows vm name
* add memory to kvm as win10 needs 1G
* increase win VM timeout because win10 seems slower to start
* add an option to keep build dir for debugging purpose

Deprecates the previous pkg_resources-style packages. Our use was
not entirely spec compliant, and it broke with setuptools 31.
More information in https://github.com/odoo/odoo/pull/15718

Instead, use the pkgutil-style namespace packages.
This is spec compliant as long as all other distributions providing
odoo.addons use PEP 420 namespace packages (i.e. no __init__.py).
So this mechanism fully works on Python 3 only, but does not break
anything on Python 2.

Complements 021de21e and #16918

In Python 3:

* various builtins and dict methods were changed to return
  view/iterable objects rather than lists
* and the separate Python 2 view/iterable builtins and methods were
  removed altogether

This is problematic when using these items as list (which the happens
repeatedly in Odoo), but more viciously when iterating *multiple times*
over them (which also happens, which I've messed up multiple times while
writing this, and which is a pain to debug even when you've just created
the issue).

Convert all code using these to semantics-matching cross-version
helper functions to get the LCD behaviour between P2 and P3, and
forbid the builtins via lint.

* thin compat module stripped down from werkzeug (to augment as needed)

In 07bf7bf4 a fix was introduced for windows server UTC timezone.

It is possible it would be helpful in some situation to also have it in
setup/odoo (for example if odoo was installed on windows in some other
way than the Installation bundle).

Before this patch, the debian package depends on `python-pybabel`.
According to the documentation, this is a dummy package for transition
from `python-pybabel` to `python-babel`[1].

This dummy package has thus been removed in debian stretch in favor of
`python-babel`, and the odoo package is thus not installable in debian
stretch.

To fix this, we depend directly on `python-babel`, which is available in
all debian releases[2].

Closes #13905

Without this, odoo log outputs to stdout and is catched by journald. We
force the use of a log file to keep the behavior consistent with the
debian package.

by auto-extending addons path with odoo.addons.__path__.

This patch also introduce
  * an explicit declaration of odoo.addons as a namespace package
    This is necessary because the standard way of declaring namespace
    packages in setup.py does not work as long as odoo/__init__.py
    contains code.
  * a more reliable way to find odoo root path.

no fallbacks were implemented to `openerp-server.conf`.

Creating a centos docker image fails on our nightly server with
this issue: https://github.com/docker/hub-feedback/issues/461

To create a centos image, we used another repository to host the
image and we make it build in docker hub, then we pulled it. It
was getting really annoying.

The use of an entry point was considered in order to provide
an `odoo` command in the path for the packages users, but the
generated entry point will first check that all the things in
install_requires were provided in a not bright way: it'll check
that it matches a distribution name. This does not work because
python-chart does not have the distrubtion name "pychart" which
is provided by the python-pychart package in debian jessie. Same
for suds-jurko which is provided by python-suds in debian stretch
but does not have the distribution name "suds".

Also, adapted the  packages tests to these cli changes.

and move it under the setup package. Since the rename of the
openerp directory into odoo, having a script named "odoo.py"
conflicts with a package named "odoo".

This way we do not have to pass the version as argument. This
was error prone. If the timestamp has to be included in the
version, just patch it during before running package.py. This
was already done in our nightly servers anyway.

Correctly pass it to the nsis script the same way it was done for
the version and python version. this was a source of error at each
release.

Fix the various place when the rename of the git root directory
broke the packaging script. Also, we can now name the library
"odoo".

* Remove dependency on less-plugin-clean-css which distribution
  packages are broken on debian stretch and derivated.
* Updated documentation.
* Lessc provides a `--compress` argument that could solve this issue.
  According to the documentation at http://lesscss.org/usage/: "[...]
  Compress using less built-in compression. This does an okay job but
  does not utilise all the tricks of dedicated css compression[...]"
  However, using this argument works on lessc 2.5.3 but not on 1.4.2
  (`--compress` arg is present but seems to be break some rules
  i haven't been able to put my finger on).
* Finally, use the minification of the StylesheetAsset that takes care
  of removing the spaces, the comments and the sourcemap with regexes.
