Timeout/max duration for attempts

We have maxDuration for runs, which is the maximum compute time for a run. If it exceeds that the run will fail with a timeout error. This is especially useful in situations with recursion or with APIs that sometimes just hang and never reply or fail.

But it would also be useful to have a max time on an attempt. If that time is exceeded the attempt fails, and if you have remaining retries it would reattempt.
