I would be extra safe and do a check here that these exist in the dictionary. The annotations section is entirely optional (if you don't believe me, you can verify this with promtool). Right now all the alerts we have a summary, but we don't have documentation for OCF alert standards, so some could eventually slip in without it.

This is pretty much a copy of the code from #76.
We'll start off with the #rebuild-spam channel for now, but if this works out well we can extend this to use custom channels (configured by Prometheus) and then utilize the #opstaff-alerts channel.
It looks like this:
