During metric meeting, we have discussed about auto resumption records multiple Download.InterruptReason.

Should we only record the first error instead of every error in the retry?

Or we can separate the error in the retry to another histogram, and Download.InterruptReason only records the first error. 

There is also discussion about the retry errors can be different from the first error. So I think another histogram like Download.AutoResumption.InterruptReason probably makes sense.
