Issue BAM-3804: Prevent a build from running if its ancestors are in queue or running
E.g. B depends on A if B is triggered whilst A building, B trigger is ignored. This will mean that further checkins against B won't run. Have to be optional. Must only block if the parent is the same revision as the child that is about to build, otherwise, the child might never build.
