P4
There are two reasons for configuration the PR bot on a repository.
1. Process PRs
2. Process commit commands
Most of the time we want both of these, but sometimes, a repo exists only for commit command processing (typically /backport). For those repositories, we would like to configure them to not even allow PR/MRs, to avoid having users doing so in error. This is currently not possible, as (at least) GitLab will return 403 when listing merge requests for a repository where they are disabled, which in turn causes getPeriodicItems in the PR bot to fail.
To solve this, I would like to make it possible to disable PR processing for a repo through configuration. Perhaps we should also make commit processing optional for symmetry.
