refs #5184 - fix couple of issues when deleting foreman hosts

This commit addresses a couple of issues that were observed with the
foreman host <-> katello content host integration, in the production
configuration.

1. Deleting the foreman host would result in a 404 to the user.
2. Unregistering a content host and visiting the foreman host would
   show an 410 error to the user.

The key issues that caused these were:
a. There were 2 bindings of the host extensions to the host.  This
   triggered the deletion of the content host twice.
b. The model relation for host and content_host did not have the
   proper 'inverse_of' definition, so it could lead to foreign key
   errors.
Fixes #6008 - Puppet environments synchronization capsule synchronization
Fixes #5759: Make search and filtering on Content View Filters work as intended.
Fixes #6005 - speeding up content reindexing

Instead of indexing per repo, we can index all of each content
and it will be much faster.  Sample times with a content view with about
5 versions:

Old Reindex: 7m05s
New Reindex: 3m13s

the more content views and versions you have the greater the difference

Fixes #6026 - Fixed repo list api call for no env case.

If you have a content view in library published few times and promoted a
few times

hammer repo list --organization-id=1 will return all repos across all
content views and environments. Meaning it will return repos with the
same name 10 or 20 times.

Ideal behaviour would be to say something along the lines of "If you
dont pass me an environment I am going to assume library/default content
view version."
