There are generally multiple repos that share the same IssueProject. It would be possible to have one single CSRBot for each IssueProject and just loop over all the repos in it. I chose to split them to keep each "bot" more focused on polling one kind of thing. Compare with the existing `MailingListArchiveReaderBot` and `MailingListBridgeBot`.

I do agree that part of the implementation here would be nice to be able to reuse, but until we know how some other bot would like to reuse it, I would rather not complicate the current patch further.

Also, thank you for taking the time to review this!
