fixes #6442 / BZ 1090643 - content view - add support for content view copy/clone

This commit contains the changes to support creating a new content view
as a copy of an existing view.  This is to bring back functionality that was
lost during the content view rework.  The copy operation will only copy
the 'structure' of the content view (e.g. repos, filters, puppet modules,
details) and it will not copy the published views, history or tasks.
Fixes #6457,BZ1115089 - Match multiple items on contents changed

The problem when uploading multiple items is that we were doing a unit search
that could have multiple results but we were only looking at the first one. We
need to get the ids of all.
Fixes #5181/BZ1110955 - filter available for composte CV server side.

The bugs mention that the total is incorrect when using the select all
control.  This was due to Bastion transforming the response from the index
call on Content Views and hiding non-applicable results.  This commit
moves that logic to the server side where it belongs.
