Cluster: handshake "already known" error logged to VERBOSE.
Cluster: handshake "already known" error logged to VERBOSE.

This is not really an error but something that always happens for
example when creating a new cluster, or if the sysadmin rejoins manually
a node that is already known.

Since useless logs don't help, moved to VERBOSE level.
