The scheduler runner will route the save code now queries to those queues.

doco up with patched scheduler with D5520 and checks through save code now ui that
requests are routed to those queues defined here (well i only tested git but still)..

I even went along and commented the default update git queue from the loaders worker and
checked that queue was not created (only the save_code_now:... is and save code now
origins are consumed properly!
