AFAICT you seem to be right that this call doesn't need to block for B.

Why 1000 retry attempts and 5 seconds delay (I believe it's a delay between attempts, not overall)? I think, the EndTranscodingSession goroutine will finish instantly here. Also maybe pass options to VerifyNone call directly?

Thanks @cyberj0g. Unfortunately for the tests the communication for the EndTranscodingSession call isn't set up so it simply times out after the 3 second timeout, so that's the reason for waiting. And the other annoying thing is the goleak library starts off with very small microsecond pauses between retries so that's the reason for the high number.
I've looked into a lot of different ways of abstracting this away for the tests without success, I think it'll have to wait for a later PR.

Builds were failing on master like this: https://github.com/livepeer/go-livepeer/actions/runs/4309780285/jobs/7517555365
It seemed as though the wildcard matching was not working. @hjpotter92 made some changes in this area recently so I'll check with him when he's back but the change I've made has fixed the issue in any case.
