Create Job Queue for transfer tasks

[consolethinks]

Add a queue for dataset transfers to PSI

[phwissmann]

Regarding the job queue: are there any strong requirements not yet considered here #12 ?

I'm thinking

• Prioritization (how relevant is it)
• Manual interaction (cancel, reschedule)

But not sure what is really relevant.

I've already create an Epic #6 for the job system so #32 could concentrate on the other functionality and just about creating the job itself. What do you think?
