Description of problem:
As of now, we do not check in health check if Satellite FQDN is set or not. So before configuring new DNS, DHCP or updating certificates we should have foreman-maintain health check run and it should check proper FQDN.

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

Actual results:

1. foreman-maintain health check
