Adrian Likins 27a015f0ad add a 'min' type for gather_subset to collect nothing (#27085)
previously gather_subset=['!all'] would still gather the
min set of facts, and there was no way to collect no facts.

The 'min' specifier in gather_subset is equilivent to
exclude the minimal_gather_subset facts as well.

   gather_subset=['!all', '!min'] will collect no facts

This also lets explicitly added gather_subsets override excludes.

   gather_subset=['pkg_mgr', '!all', '!min'] will collect only the pkg_mgr
fact.
