Bypass specified procedure to completion. Procedure is marked completed but no actual work is
done from the current state/ step onwards. Parents of the procedure are also marked for bypass.
NOTE: this is a dangerous operation and may be used to unstuck buggy procedures. This may leave
system in incoherent state. This may need to be followed by some cleanup steps/ actions by
operator.
