Subject: [PATCH] retry.Retryable(): re-try MySQL error 1047 for a "not yet
 prepared node"

During start a Galera cluster complains with "WSREP has not yet prepared
node for application use". But the error code, 1047, stands for "Unknown
command". So re-try only a "not yet prepared node", but not an "Unknown
command".
