Retry button

[sj26]

We sometimes get an transient error in the middle of a maintenance task. Automatically handling these is ideal, but requires anticipating all errors. What I'd really love is a "Retry" button on an errored task, like this:

I believe it would involve a button and endpoint there, and then a state transition on the task run back into a running state, resuming at the errored element, like unpausing. Is that something you would consider accepting as a contribution?
