Database instance status
Trove is maintaining two types of status, named status
and operating_status.
status is reflecting the trove instance VM status and
instance task status, e.g. after successfully creating a trove instance,
the status is ACTIVE, when doing backup, the
status is BACKUP, etc.
operating_status is the actual database status inside
the trove instance, trove guest agent is actively monitoring the
database status and reporting back to trove, e.g. when MySQL service is
up and running, the operating_status should be
HEALTHY, if MySQL service is not running for some reason,
the operating_status is SHUTDOWN.
