Dustin J. Mitchell 91f4fe8c61 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.
