cubicweb-pyramid #4783342 --debug should enable --reload [validation pending]

--debug is expected to enable all debug options for debugging.

In cubicbweb-pyramid, it only activate --no-daemon and add the debug_toolbar.

To make things more consistent, we should have:

 Enable the debug toolbar
--reload Enable auto-reload
--no-daemon Run in foreground
--debug Equivalent to "--debug-toolbar --reload --no-daemon"

This goal may not be totally achievable because --debug-toolbar would need to activate the repository debugmode.
