Fixes #6553/BZ111225: add "repositories" to product resource type name.

There was some confusion about Repository permissions being underneath
Products. This commit simply updates the resource type name to make
it obvious that repositories are also affected by these permissions.

Fixes #6551/BZ1112644: show add/remove content hosts if user able

The permissions that show and hide the UI for adding/removing
content hosts to/from a host collection were incorrect.  This commit

fixes #6512 - move valid notices routes inside resources block

In Rails 3.2.8, it's not seeing the previous notice route get_new as
being part of the engine.  Moving inside a resource block fixes that
problem.  I also removed 2 routes that aren't valid and shouldn't exist
anymore - note_count and auto_complete_search.
fixes #6461 - create Katello permissions without quotes in db seeds

Katello seeds was creating incorrect permissions in the Foreman DB by
adding a set of superflous quotes -- e.g., "'Katello::ActivationKey'".
This commit removes the extra quotes.
