Bug 1470622 switched to hook-based actions for Treeherder (e.g. for retriggers).

Sometimes these retriggers fail, even after logging out and in and reloading treeherder:

See e.g. https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&resultStatus=success,pending,running,testfailed,busted,exception&revision=28baa3df5f0f530faee1900f43c463f6b77b985c&searchStr=retrigger

If treeherder had to roll back, there would be errors from buildbot shutdown.

[task 2018-09-14T11:08:16.263Z] KeyError: u'path'

It looks like the issue here is that these are mochitest retriggers, which expect input as to what mochitest to run, etc.  Treeherder isn't giving them that input.

Probably:
 * We should define a minimal input for all of the pre-defined action names (including retrigger). Probably {} for most.
 * We should adjust all of the retrigger options to accept that input and do a basic retrigger

Hassan, does that seem like a good fix?

So to be clear, this affects only mochitests.

Seems like a good fix.

Summary: new treeherder hook-based retriggers often failing → hook-based retriggers failing for mochitests
Even with no options, this is not a simple retrigger -- it adds voluminous
debug output.  So let's keep it as a custom action.

IIUC, this bug is the reason that we can't currently cancel jobs on mozilla-release or mozilla-esr60 from Treeherder. I took a look at backporting, but there's a number of dependencies and conflicts. Dustin, can you please sort out what needs uplifting to get this working on the remaining supported branches?

FTR, here's the error I'm getting (on Beta too, actually):
Taskcluster: No such hook --- * method: triggerHook * errorCode: ResourceNotFound * statusCode: 404 * time: 2018-09-20T20:24:32.941Z
Fixed that with a ci-admin run.
