[hooks] Change get_user_sessions prototype, necessary for hijacking from other session implementations (e.g. pyramid)

Store user groups and properties as session data * stop retrieving them systematically, only when need, * reimplement session synchronization hooks with some cleanups along the way, * cleanup call to set language: not needed from the base request nor from the server side, only for the web request (on the server side, language is necessary only for notification and such code should set it explicitly). There is still a XXX remaining about one can only "enter" a connection once and this is a problem in some cases. IMO, this restriction could be removed. Closes #13500113.

[skeleton] Remove override_dh_python2 We do not ship files as "data files" anymore. Related to #13001466.

[skeleton] Have setuptools install data files Just add `include_package_data=True` as recommended by `setuptools documentation`_ as this appears to be the simplest way to handle this. Related to #13001466. .. _`setuptools documentation`: \ http://setuptools.readthedocs.io/en/latest/setuptools.html#including-data-files

[skeleton] Update MANIFEST.in following new "package" layout Related to #13001466.

[skeleton] Add python-setuptools to Debian Build-Depends Related to #13001466.

[skeleton] Add dh-python to Debian Build-Depends Related to #13001466.

[skeleton] Copy files mode bits (debian/rules in particular)

[doc] Start filling changes/3.24.rst with recent changes

[doc] Drop commented mention of "live-server" command Follow-up for d83676aaea21.

[pyramid] Drop guard of old cubicweb version

[pkg] Declare extras (optional) dependencies This is primary to extract "pyramid" dependencies out of install_requires as they are actually optional. Along the way, resurrect all things in __pkginfo__.__recommends__ which were not used at all and convert them into extra_requires. It appears that __depends__ and __recommends__ in __pkginfo__.py are not useful so drop them and inline dependencies as install_requires/extra_requires in setup function call. For pyramid tests to continue working, add respective dependencies to test-misc.txt requirements file.

[tox] Exclude all files in symlinked directories from check-manifest call

[tox] Get rid of "touch test-results.xml" for flake8 and check-manifest environments CI server does not rely on this anymore.

[debian] cubicweb-pyramid conflicts and replaces pyramid-cubicweb Related to #14023058.

Merge cubicweb-pyramid cube Only keep the CWSession schema definition and the ctl command, now in cubicweb/pyramid/pyramidctl.py Related to #14023058.
