Description of problem:

Applying errata via Host Collection the errata are trying to be applied to all hosts associated with the host collection.

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

6.6

How reproducible:

Create a Host Collection, associate some hosts on this host collection, try to apply an errata that affect a few hosts from this Host Collection via WebUI going to:

   Host > Host Collection > Click on the Host Collection > Errata Installation > Select an errata that affect few hosts > Install Selected


Steps to Reproduce:
1. On the Satellite WebUI try to apply an errata on the hosts associated with a Host Collection

Actual results:

The Satellite will try to apply the errata on all hosts associated with the content view. i.e. If you have 1000 hosts but you would like to apply an errata that affect just 100 hosts, the Errata Job will access the 1000 hosts trying to apply the errata even this errata would not be available for those hosts.

Expected results:

The Satellite tries to apply the errata just on the hosts affected, not on all hosts associated with the Host Collection.

Additional info:
The Satellite is generating a task for all host associated with the Host Collection, it can cause a high load on qpidd in case trying to apply the errata via katello agent.
