Adds support for fetching deployables from conductor client

This pull request uses the update conductor api to pull deployable information.  After applying this pull request, you should be able to log into a conductor provider and, after clicking on "Launch a New Application", view a list of available deployables.

Currently, the conductor api does not support deep listings, so we have to make n + 1 calls to the API (1 for the list of deployables, and then n for each deployable).  Once this is updated in conductor, we can update this code.
