Filter Packages Admin by Catalog and/or Manifest

[selfcommit]

This issue is being presented as an opportunity for the Github community to make any further suggestions about implementation before an attempt is made to implement a solution.

Work will start on or about July 13

Details from the Simian feature request doc are below:

Problem:
For instances where many (>100) packages are present, identifying packages targeted at a particular track of devices requires a lot of scrolling.

Solution:
Add filtering functionality to the UI to only display packages which are targeted to a set of catalogs and/or manifest.
