Backport riak-cs-debug update from 2.1

[ksauzz]

Main purpose is to support a Riak CS deployment such as using app.config and vm.args only.

• gh1236 is needed to gather vm.args
• gh1263 is needed to work with app.config and vm.args only

The difference between this branch and 2.1 is only riak-cs-admin status.
