Implement search for Composer repositories

[fjmilens3]

Right now we have no format-specific search for Composer repositories. We should try to add this, with a selection of search-indexed format-specific fields based on what we come up with for #3 in terms of relevant metadata.

Note that I'm unsure we're doing this for the public R plugin either, so we may have some unknowns about how to:

• Register the elasticsearch-mapping.json file and any custom search code that may be required.
• Register the search UI component/form (e.g. SearchComposer) with Rapture (our own ExtJS-based UI framework).

Also pinging @DarthHater to see if he remembers if we don't have that for R, as it's been too long for me to remember the particulars (did we had a technical reason that might need us to look at our existing implementations?).

I have a branch of this for R somewhere. Just never got it out. Thanks for nudging me!

This will likely require someone from within Sonatype to work on as it relies on an understanding of search implementation and UI implementation within Nexus Repository Manager.
