[pyramid] Let logging be configured through .ini file We do not initialize logging in CubicWebPyramidConfiguration thus preventing logging to be started with cubicweb's configuration. On the other hand, any logging configuration defined in ``development.ini`` file will be loaded by whatever start the instance using this file (i.e. pserve, gunicorn, etc.). The benefit is that logging can now be configured per "qualified name" in this file (i.e. one can easily set the DEBUG level for the application cube while keeping all dependencies' level to WARNING). In the development.ini template, we add logger configurations for "logilab" and "cubicweb" qualified names (along with those of the application cube).

Disable pytest's logs reporting CubicWeb already prints captured logs in stderr upon test failure, so we get them twice. Until we fix our logging management, disabling pytest capture and restore brings the output level back to sanity.

[pyramid] Do not issue security warnings in test mode When some session or authtk secret is missing in Pyramid settings, scary "!! SECURITY WARNING !!" are issued. This is arguably pointless in tests. So disable them in this case.
