fixes #3105 - use untranslated string for PuppetCA state filter
fixes #4375: provisioning no longer loops when using oVirt + compute profile
Fixes #4596 - Change parent of host group via AJAX

Reparenting host groups requires submitting the form to see the changes

from the parent and show them in real time.
Fixes #7041: fixed incorrect belongs_to mappings

:conditions reference columns from the local (to the relation) table,
