Fact collector ordering deps (#31362)
Add deps/requires for fact collectors

Fact collectors can now set a required_facts
class attribute that will be a set of the names
of fact collectors they require to be run first.

ie, if a collector needs to know the ansible_distribution,
it should set it's required_facts to include 'distribution'

        required_facts = set(['distribution'])

If a collector requires another collector, it gets added
to the selected collector names.

We then topological sort the ordering of the collectors
so that deps work out (ie, 'distribution' will run before
'service_mgr')

required_facts were added to the collectors for:

        - network (requires 'distribution', 'platform')
        - hardware (requires 'platform')
        - service_mgr (requires 'distribution', 'platform')

Fix name references for facts (need 'ansible_' prefix)
is service_mgr

Fixes #30753
