  ovn: Add '--restart' flag to ovn-controller exit.

When "--restart" is passed to ovn-controller's exit command, then
database entries are not removed for this hypervisor. This means that
* Encaps
* Chassis
* OVS ports
are not removed.

The reasoning is that if the intent is to restart ovn-controller, this
will allow for tunnels to remain up and allow for traffic not to be
interrupted during the restart. When ovn-controller is started again, it
picks back up from where it was.

  ovn: Modify restart_controller in ovn-ctl to use --restart

The --restart flag allows for uninterrupted packet flowage when exiting
ovn-controller. This patch modifies the restart_controller argument to
ovn-ctl to use --restart.
