fc: initial pull request evaluation support

The migration adds PR support, models expose PR fields, webhooks handle
PR events, and tests validate it. To be honest the migrations are a bit
redundant at the moment, but I'd like to handle my old deployments so
it's nice(r) to have them. I *am* testing those on baremetal.
