The new `overrule-shutdown` parameter is boolean and defaults to 0. If
it is 1, all active `vzshutdown` tasks for the same CT (which are
visible to the user/token) are aborted before attempting to stop the
CT.

Passing `overrule-shutdown=1` is forbidden for HA resources.

Notes:
    changes v2 -> v3:
    - avoid printing empty list of overruled tasks
    - rephrased parameter description/commit to reflect changed logic
    - adapt to rename to `abort_guest_tasks`
    
    changes v1 -> v2:
    - move overrule code into worker, as suggested by Wolfgang
    - print to worker stdout instead of syslog
