CLI displays which bosh deployment file

Removed a redundant call to deployment_required

Change-Id: I492e6155a8cd6578792611feba7b6ac35e2ff2c8
Add gemspec for bosh agent.

This does not replace the Gemfile yet due to some remaining issues with
dependency selection by platform. I plan to use it to build the gem and
vendor it in the micro repo.
