feat(gerrit): add code-owners plugin

This is the New Thing that is intended to replace the find-owners
and owners plugins.

In particular:

* It inserts a submit requirement rather than providing a Prolog
  predicate.
* The default OWNERS file formats are suspiciously Googley.
* It provides a neat UI for finding OWNERS and tracking approval
  state on a per-file basis.

When we fully migrate to using the code-owners plugin, a few
things will need to land, which I will likely do "offline"
directly to the Gerrit backing Git repos:

* Add the corresponding Gerrit config
* Replace OWNERS files depot-wide
* Add OWNERS files to the refs/meta/config branch
* Introduce the Owners-Override label, settable by depot-interventions

The enclosed patch adds two extra pieces of functionality that
we need in tvldepot but aren't upstream:

1. The ability to just specify usernames rather than email addresses
2. The ability to specify `group:GROUPNAME`, _as long as_ that group is
   visible to everyone. This is a restriction intended to avoid having
   the plugin just leak group membership.
