RFC: Support dynamic reconfiguration of "buckets"

[mattmoor]

/area API /kind feature

I mentioned this in slack, but given that we already support being promoted to and demoted from "leader" dynamically, could we support dynamically changing the bucket count by:

1. Demoting all the current buckets,
2. Promoting new buckets as we gain ownership of them.

I haven't looked deeply into what this would entail at a code level yet, but I wanted to float the idea for broader discussion.

@mattmoor @dprotaso could we re-open that issue ? I think it's still a valid thing to work on 👼🏼
