This will reduce the need for many workarounds that are currently in place.

I've started work on this - not complete yet. Work will go in this PR, and I'll add a comment here when it is ready for review.

Just about ready now. There is a unit test which is passing, but I'll add an integration test tomorrow.

Ah - and I'll need to handle credential updates during task execution - so still a bit of work to do. Credentials can get updated while the task is running, which we'll need to handle. There is a taskcluster-proxy endpoint for handling this, so it shouldn't be too tricky.

This is done now - although I don't have a test which explicitly checks that the credentials PUT updates work - just because that would involve a bunch of mocking or customising the reclaim timings so a test could reclaim more quickly than waiting 20 mins. Oh, I guess I should do that, just to be safe... I'll do that shortly. Aside from testing the credentials PUT update to /credentials works against taskcluster-proxy, the rest is implemented and has tests.

OK, I think I'm done - just waiting for tests to run.

I'll fix the tests on Monday morning - nothing serious, just some roles need to be updated, and some PATH settings...

Oh, and a data race... Shouldn't be too much work to fix.

The issues are resolved now, and the tests are all passing.
