This is an experiment to allow a leader to request a snapshot from a follower. The idea is that the leader can, during normal operation, delegate the task of creating snapshots to the followers. This makes sense under the following assumptions: the snapshot is relatively small, but expensive to compute. Requesting a a ready made snapshot from a follower, offloads this task from leader and avoids blocking leader. This implementation is not complete, only for experimentation.
