Bug 1398277: special-case retriggering of tasks not in the taskgraph; r=bstack This will apply to cron tasks, action tasks, and decision tasks. It is a distinct retrigger implementation because (a) we do not want to follow dependencies, and (b) it takes a lot of scopes to create a decision task, so we need to limit access to this action.
