Bring Nomad in line with other HashiCorp projects and remove stalebot. We get
little value in cleaning up issues automatically this way, it adds extra work
for maintainers when we have issues waiting on the backlog that we intend to
do, and it presents an unkind experience to issue contributors who get their
issues closed by an impersonal bot.
This runs ember-test-audit for UI PRs to compare how long
the tests take for the base vs the PR. It posts or updates
a comparison of times and test count.
It’s somewhat slow to report back as it runs the test suite
three times to even out variability in a shared environment.
If we end up being unhappy with that slowness, we could try
running the repetitions in parallel as well, but that would
involve more changes to ember-test-audit.
This uses a fork of the Ember Asset Size Action to report on changes to
the filesizes of the production UI build as a comment to the PR. The
fork includes fixes to make it work with a subdirectory (ui/ in our
case) and to make it update the PR comment if it exists vs posting
repeatedly to the thread.
