Skip tests for ldapsource with python >= 3.7
Until someone works on fixing these, this should make our CI green
again.
I tried to use setupModule() to check for python version, but
pre_setup_database() is apparently called even when a SkipTest exception
is raised there. So handle this in that method.

The facets system
-----------------
Facets allow to restrict searches according to some user friendly criterias.
CubicWeb has a builtin `facet`_ system to define restrictions `filters`_ really
as easily as possible.
Here is an exemple of the facets rendering picked from our
http://www.cubicweb.org web site:

Facets will appear on each page presenting more than one entity that may be
filtered according to some known criteria.
