[llvm-dev] Managing buildbots through the Web UI

[Michael Kruse via llvm-dev]

Rights to do actions are listed in
https://github.com/llvm/llvm-zorg/blob/f09bb849f94c1fbf105185bc0ff164e2a421f638/buildbot/osuosl/master/config/auth.py#L21.
The role you are in is determined by github:
https://github.com/orgs/llvm/teams. I don't know how the "owner" and
"worker-owner" are determined, but I can stop build from by own
workers (But ironically, I am not allowed to control the worker
itself, e.g. pause it). In a previous exchange Galina mentioned that
the email in the worker's info/admin file must match the primary
GitHub email.

Considering that builds on that bot take less than 10 minutes, that wait time means that the bot spend more than half its time waiting rather than doing anything useful even though it has a lengthy queue of requested builds.
