If a "stop" on the mysql init script does not work, the init script
should be removed.

Bug description:
  [ impact ]

  Previously, init.d scripts that were replaced by upstart jobs had
  "upstart-job" symlink as a redirect in-place, which directed users at
  using upstart commands. Despite the good intentions, that never
  actually taught people about the correct interfaces. Now with the
  advent of co-installability of multiple init systems, users may have
  systemd, upstart, and sysv-init all installed on users system and have
  init.d scripts / upstart jobs / systemd units all available. To avoid
  any daubt, we should support executing /etc/init.d/ scripts which may
  call into upstart, or into systemd, or actually execute the script in
  question depending on whether there is native configuration for that
  particular job and which init system we are running under.

  [ test case ]

  Invoking init.d script should invoke upstart commands, for example:

  $ /etc/init.d/ssh status
  ssh start/running, process 4620
  $ /etc/init.d/ssh stop
  stop: Rejected send message, 1 matched rules; type="method_call", sender=":1.2469694" (uid=1000 pid=3908 comm="stop ssh ") interface="com.ubuntu.Upstart0_6.Job" member="Stop" error name="(unset)" requested_reply="0" destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init")
  $ sudo /etc/init.d/ssh stop
  ssh stop/waiting
  $ sudo /etc/init.d/ssh start
  ssh start/running, process 5373
  $ sudo /etc/init.d/ssh restart
  ssh stop/waiting
  ssh start/running, process 5405

  In Ubuntu 13.10, the Upstart job and the init.d script do not work
  properly.  In previous versions, the init.d script was a symlink to
  the wrapper script around upstart (/lib/init/upstart-job).  This
  conflict means that if the server was started using the init.d script,
  upstart does not recognize that the server is running and will attempt
  to start a second instance of mysqld.

  Also problematic is that if the upstart job is started using the
  service or start commands, the init.d script's "stop" function runs a
  mysql shutdown, but upstart simply restarts mysqld (because it's
  marked respawn in the upstart config).
