wip-6033-redirects
The Objecter half of this is done and seems to be working correctly. The OSD portion is a bit more complicated; I currently have some truly stupid logic that just issues a redirect on any tier pool which doesn't have the object requested. (So there's no promote/demote logic, and there's nothing like determining behavior based on the cache type.) I think I'd like to discuss the best place to put that logic before moving forward.

The OSD is slightly less stupid now, and it looks like making it smarter is going to be part of future tickets (the cache modes don't really make any sense without doing promotion/demotion of objects).
Ready for review: https://github.com/ceph/ceph/pull/580
