The teams named in this revised version of the `CODEOWNERS` file are
currently configured with the same members as are listed in the file
now.
We wanted a single member of the selected team to be assigned as a
reviewer, but listing people explicitly in CODEOWNERS causes all the
named people to be assigned. Using teams instead allows us to configure
the load-balancing policy.
This also will allow us to add and remove reviewers without needing a PR
every time.
We want to make sure every contributor gets some kind of meaningful
response in a timely fashion. To that end, this PR configures GitHub to
auto-assign somebody to every newly-opened PR.
People must only be added to this file if they've agreed to this
obligation. The details of what's expected are listed in the file. I'll
only merge this if it's signed off by everyone listed in this initial
version.
