"Emergency" queue to force all resources on a specific evaluation(s)

[cole-h]

11:10 <gchristensen> it would be nice if there was a button of "ignore the rest of the rules, do nothing but this evaluation until it is done."

Earlier today, an exploit in sudo was announced. Nixpkgs quickly updated to the latest patch, but now we have to wait for all the other Hydra machinery to finish before the evaluations queued with this fix in it can run. It would be extremely useful to have some button that would allow someone to put an evaluation at "maximum priority", where all the other machines would finish what they are doing and then collaborate on that specific evaluation. Once all "emergencies" have been dealt with, Hydra would go back to normal.

You can go to a jobset eval and select "Actions -> Bump builds to front of queue".
