Fixes #7947 - Validating package checksums when syncing

Check the package checksums after they are synced. This will tell if packages
are corrupt, partially downloaded, etc. Decided to make a config option to
disable it too as checking decreased the performance of the sync by about 40%
(observed 1 hr 12 min without validation for a RHEL 6server kickstart repo and
1 hr 40 min for the same repo but with the checksum validation enabled).
Refs #7423: Convert to using Bastion core to provide the Katello UI.

This commit removes the components that have been transitioned to Bastion
core and changes the engine to bastion_katello. Further, dependencies
in both the re-named engine and Katello are removed that no longer apply.
Refs #7733: Remove usage of Host fixtures in favor of Host factories.

Foreman is moving to the use of factories for testing and removing
the host fixtures from usage. Here we change out our reliance on
those host fixtures in favor of the factories.

fixes #7754 - Adds cloning of activation key, BZ 531307
fixes #8087 - Locations - update to allow proper use of nested locations

Without this commit, the user can click 'Nest' to created a nested
location; however, they cannot actually assign a parent location.
As a result, nesting really isn't functional.

This commit will conditionally remove the 'parent' for organization
taxonomies, but leave them in place on the location taxonomies.

This can be tested using the following:
- new & edit org - confirm there is no 'parent'
- new, edit, nest location - confirm that user can select a 'parent'
