Live migration happens in the background, but it is useful to make the monitor
command appear as if it's blocking. This allows a management tool to
immediately know when the live migration has completed without having to poll
the migration status.
This patch allows the monitor to be suspended from a monitor callback which
will prevent new monitor commands from being executed.
