Original change's description:
> [testsharder] Sort tests alphabetically within shards
>
> Sorting tests by duration within shards means that test duration CIPD
> package rolls can cause hard-to-debug failures in non-hermetic tests,
> and the burden of debugging those failures is on me (as the owner of the
> test-durations-roller) and build gardeners in the case of flaky failures
> that are able to get through CQ.
>
> Ordering alphabetically should all but eliminate these kinds of
> failures.
>
> See bug for full rationale.
>
> Since it drastically re-orders shards, there is a chance that this
> change itself breaks some non-hermetic tests, so I'll keep a close eye
> on things after it lands. I'll also run all internal global.try builders
> on this change make sure that it won't break internal CQ.
