RecoverCluster does the following:

• attempts to apply all snapshots, oldest to newest.
• applies all remaining log entries
• creates a new snapshot, inserting provided configuration into snap
• returns

It might be cleaner (less changes to Store object) to simply implement this directly in the Store code itself.

Surround it with

• check peers.json exist logic
• decode it
• apply it (custom "recover cluster")
• delete peers.json, or move to new file to indicate it was processed, and as a record.
