Allow PhabricatorWorker->queueTask() to take full $options

Summary:
Ref T9252. Currently, queueTask() accepts $priority as its third argument. Allow it to take a full range of $options instead. This API just never got updated after we expanded avialable options.

Arguably this whole API should be some kind of "TaskQueueRequest" object but I'll leave that for another day.

Test Plan:

• Grepped for queueTask() and verified no other callsites are affected by this API change.
• Ran some daemons.
• See also next diff.
