Make saltutil.sync_all output more meaningful

The default (nested) outputter makes lists of lists look odd. So,
instead of returning a list of lists, return a dict with the keys being
the names of the different custom types, and the values being the lists
of modules of that type that were synced.

Fixes #5964.
Add a state integration test case for #5940.

Create a NO-OP mixin to shut up pylint. Fixes #5989.

Craeted a simple new style class to make pylint shut up, because SaltLoggingClass can't subclass `object` directly:

     'Cannot create a consistent method resolution order (MRO) for bases'
