* WIP: add k8s grouper
- This shares a great deal of behaviour with allGrouper. Once it's
tested, refactor that to share as much as possible
- Glide hell. Checked in the yaml and lock files but a glide i -v
will be required to bring vendor/ up-to-date. Will address once this
is ready.
* Update README. Make the watch tracking work.
(To follow: add the junk that was pulled in via the glide update.)
* Vendor updates.
* go fmt
* Use the allGrouper with a k8s-backed DBStore instead.
This is much tidier :-)
* Fix up go vet
