The issue:

Currently we support only Pagure for doing async blocker review discussions. For production, we use the [blocker-review](https://pagure.io/fedora-qa/blocker-review) repo.

Since we're migrating from Pagure to Forge, we would need a change in blockerbugs that would drop Pagure support and introduce Forge support for blocker discussions.

This means:
a) implementing reading, creating and editing a Forge ticket through its API
b) figuring out how to get notified when a Forge ticket is updated (in Pagure, we do this through a webhook)
c) figuring out authentication with Forge, and testing for privileged members
d) fixing ticket formatting if needed

Don't forget that most of the changes can be tested through staging instances - https://stg.pagure.io , https://bugzilla.stage.redhat.com and https://forge.stg.fedoraproject.org .
