Bug 4564: Implement datastore restore from backup file

Added a singleton DatastoreSnapshotRestore class that looks for and
reads a restore file in a specific directory and deserializes the datastore
snapshots. The restore file is then deleted.

The DatastoreSnapshotRestore instance needs to be injected into both
DistributedDatastore instances which are created via separate config
system Module instances. However the only way to inject the
DatastoreSnapshotRestore instance would be to define a yang module
and service. I didn't want to go thru the overhead of all that and I
didn't want the DatastoreSnapshotRestore advertised as a service. So I made
it a static singleton that is created via a new bundle Activator class.

The DatastoreSnapshot instance is passed to the ShardManager which
passes each ShardSnapshot to the corresponding Shard actor. On
recovery complete, the RaftActor takes care of applying the restored
snapshot.
