The handler to restart mysql is using an incorrect registered variable to check if the restart succeeded, leading to multiple service restarts each time its notified. The 'Remove stale .sst' and 'Restart mysql fall back' handlers will only be notified if 'Restart mysql' is 'changed', but their when clauses were checking for 'failed'. Regardless, their when clauses can be removed. Change-Id: Icc038d17b560b24bb9bf5fdd523835102ca97030
