Description of problem:
When renaming Activation Keys in either the UI or CLI, any host groups that have been configured to use the key will not get updated.  You must manually go in an update each host group.

Version-Release number of selected component (if applicable):
6.2.2

How reproducible:
Very reproducible and happens each and every time.

Steps to Reproduce:
1. Change the name of an activation key that's associated with a host group
2. Look at the host group that has the key and find the key name doesn't change in the host group
3. Must then modify the host group manually to update the activation key name

Actual results:
Activation Key name inside the host group does change upon changing the activation key name.

Expected results:
Activation Key name inside the host group should update automatically upon renaming the key.
