Description
When creating new non-primary snapshots, attempt to delete older non-primary snapshots that are no longer useful (i.e. fully synced, no peers, and the last mirror snapshot is kept). It might need to be a new "prune" state machine that runs during the "scan local snapshots" state of the replayer.

... also delete any non-primary snapshots that are incomplete w/ zero copy-progress. This could imply that the image state, object-map, etc are missing so we might as well start from scratch.
