Retry Failed Job

[ticosax]

This is an action intended to be manually invoked that put the failed job's state back to todo, while keeping the events history.

Only integrated within django (for now)
It's an Early submission (draft) for the purpose of getting feedback the maintainers. I would like to get confirmation that's something they'd like to consider, assuming I'll push it through with tests and updated documentation.
only Tested manually on my machine as it is.

Closes N/A

Hello!

I like the idea and large parts of the work already done.
I'm not sure I think a retried status is the best though. We had issues when we introduced a aborting state, which we had to undo. I think a job can be both retried AND todo, or doing, or suceeded or failed. If we want to capture that, it would rather be, I think, an event in the events table (capturing the fact a same job might be retried multiple times).

I like the idea of Django admin actions. but this immediately bears the idea of also aborting a task through the admin, though that might be for a later PR.
