Override puppet configuration on host level does not work if specified on host group
Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1193812
Description of problem:
When editing a host it's not possible to override puppet ca and puppetmaster if the hostgroup specifies these.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Create a host group that specifies puppet ca and puppetmaster
2. Assign a host to that host group
3. Edit the host and try remove puppet ca and puppetmaster, click submit
4. The Puppet CA and puppetmaster values are back
The values are still set.
It should be possible to override these values on host level.
Assigning the host to another host group that does not specify puppet ca or puppetmaster works as expected.
