Add metrics to count the number of OWNERS cache/backend loads per change

With these new metrics we want to record how many OWNERS files we need
to cache/load per change when computing file code owner statuses. E.g.
this can help us understand better how much memory gets used by the
TransientCodeOwnerConfigCache.

Gerrit Code Review code-owners plugin

This plugin provides support for defining code owners for files in a repository.

If the code-owners plugin is enabled, changes can only be submitted if all touched files are covered by approvals from code owners.

Also see resources/Documentation/about.md.

IMPORTANT: Before installing/enabling the plugin follow the instructions from the setup guide, see resources/Documentation/setup-guide.md.
