Do not activate it with Debug anymore. We are now pushing memcached log into stdout where they will be collected by journald. When activating debug, it will log there all the requests/replies to/from memcached. This will make the journal grows fast and clutter it will (most of the time) useless information. So if memcached debug is needed for some reason let the operator says so explicitly. Change-Id: I85b6ca421d326c6e764fade66726407b905c796d
