Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1982745

Description of problem:

Rebuilding/reprovisioning a host using a new HostGroup does not inherit all the values from the new HostGroup

How reproducible:

100%

Steps to Reproduce:
1. Provision a new host using a HostGroup(i.e ABC).
2. update the same host with a new HostGroup (i.e XYZ).
3. Then rebuild the same host

Actual results:

Root password set for the reprovisioned host is from the first HostGroup(i.e ABC)

Expected results:

As the Host is updated with the new HostGroup (i.e XYZ). so all the parameters should be inherited from the new HostGroup (i.e XYZ)

Additional info:

I just notied the password field, there could be more values that are getting inherited from the first HostGroup(i.e ABC).
