Since handlers are executed in the order in which they are defined the handler to restart systemd should come before the handlers to restart mysql. This avoids the error case where the playbook is run multiple times and systemd refuses to restart mysql giving the following message: "Warning: mysql.service changed on disk. Run 'systemctl daemon-reload' to reload units." Closes-Bug: #1633472 Change-Id: I3962c0e8f9f1cf3c01a3160be4c744e9fbd1ecfe
