[cwconfig] Retrieve real path of cubes directory Since logilab-common 1.3.0, we have real path expansion modutils.modpath_from_file. But the extrapath parameter that is passed from cubicweb.schema reader may still have symlinks, so expand them here to hopefully have consistent comparison in modpath_from_file.

[server] Use CryptContext's hash method instead of deprecated encrypt method Getting rid of the following deprecation warning: :: the method passlib.context.CryptContext.encrypt() is deprecated as of Passlib 1.7, and will be removed in Passlib 2.0, use CryptContext.hash() instead.
