Unify hosts task can delete live managed virtual machines
when the unify_hosts rake task runs, it does not seem to take into consideration whether or not the host being removed is 'Managed' by the Satellite via a Compute Resource.
This can cause the machine to be destroyed!
Steps to Reproduce:
1. Create system via compute resource, or register with shortname and set to managed.
2. manually invoke unify hosts script
3. Verify host destroyed afterward, check with Monitor -> Audit.
Unify hosts removed managed shortname host, destroyed system.
Unify hosts should handle or ignore managed hosts.
