Description of problem:

Presently there are only four matcher values for overriding smart class parameters in Satellite 6 which are fqdn, hostgroup, os and domain.
It would be very beneficial to be able to use host collections as a matcher value as this is the primary grouping method in Satellite and would be a common requirement to setup unique puppet overrides on.

Version-Release number of selected component (if applicable):
Satellite 6.2

Actual results:
We cannot find any fact/YAML definition related to 'Host Collection' in any
hosts which are associated to Host collections. Fact is required in hosts to create a matcher in Smart Class Parameter.

How to reproduce:
In satellite 6 server, customer want to add below attributes:
Navigate to Configure>Classes>Smart Class Parameter>check Override box>Prioritize attribute order
#hostcollection (Host Collection)

Once this is added it is listed in "Specify matchers" drop down list where customer can select:

Attribute type Name
-------------- -------
hostcollection = APACHOSTS or NAHOSTS

Above hosts collections (APACHOSTS/NAHOSTS etc) are earlier created in satellite and contains several hosts. Based on the specific matcher, new 'values' can be passed to all hosts.

Question arises here - Is there any facts or YAML definition available in all the hosts that is part of host collection?

I checked some hosts (Monitor->Facts) and cannot find any such facts. After running #facter in any puppet hosts, I can see below several facts which can be used to create a matcher in Smart Class Parameter but cannot find any facts related to host collection -

fqdn,
os,
domain,
hostname etc

Expected results:
Cu is requesting to create a matcher based on host collection. Currently, we cannot find any facts/YAML definition related to Host Collection in any hosts.
Once fact is available it can be used to create a matcher.
