Description of problem:

The interface for adding puppet modules to a content view (in the UI) utilizes a filter of loaded puppet modules instead of allowing the user to search for available puppet modules.  This makes it very difficult locate and add puppet modules to a content when working with a lot of puppet modules (e.g. puppet forge).

Version-Release number of selected component (if applicable):

satellite-6.2.0-7.0.beta.el7sat.noarch
tfm-rubygem-katello-3.0.0.15-1.el7sat.noarch


How reproducible:
Always

Steps to Reproduce:
1. Create a puppet repo that points to puppet forge (https://forge.puppetlabs.com)
2. Sync the repo
3. Create a content view
4. go to Content -> Content Views -> [mynewview] -> Puppet Modules
5. click 'Add New Module'

Actual results:

Observe the the input box is a "Filter...".  As a result, I have to scroll until I locate the module that I would like to add to the content view.

Expected results:

The "Filter..." should really be a "Search..." that will allow me to leverage the power of scoped search on the server-side to help me locate the puppet module.
