Allow increasing job timeout

[dowusu-antwi]

What is happening?

@ColinCampbellCQ would like to run IRB jobs on lagos, and so will need to wait for a while in the queue. Thus, perhaps we should allow increasing / overriding the timeout client-side (maybe restricted by role).

What are the current alternatives?

Come up with some other framework for submitting jobs like IRB, QAOA/VQE, etc. that take a while (Runtime will help, but we'll still need to handle the timeout issue on top of this).

Any additional context?
