Make the 'Job' cells of the UI a configurable partial

[nhorton]

Your default partial for showing the info about the job you are seeing is a great default. But it would be likely simple and hugely impactful if it basically rendered a partial for that based on the Job, and let standard rails partial identification (or maybe something with a customer path setting) be used to get alternative definable partials.

Right now, with Sidekiq's UI that is very similar, we often will need to look at the arguments, find an ID number, then go look that up in another UI. Having configurable partials would let us trivially make those nicely-formatted UIs (for example, showing a name for the object instead of its GlobalID) and to hyperlink to other management pages.
