Code Issues Proposed changes

Use entry points for config generation

Browse Source 
This starts using entry points to generate configuration for the
common.config and the common.wsgi modules, as they use entries with the
same name in different groups.
This also removes configuration for sslutils which is unused, and
re-enable the check for up-to-date configuration.
