Subject: Support for restarting a persistent cluster.

Option --cluster-size=N: members wait for N members before recovering store.
Stores marked as clean/dirty. Automatically recover from clean store on restart.
Stores marked with UUID to detect errors.

Not yet implemented: consistency checks, manual recovery from all dirty stores.
