During work on https://gitlab.com/gitlab-org/gitlab/-/merge_requests/59902 it came to our attention that Atlassian [could be rolling out](https://jira.atlassian.com/browse/CLOUD-6999?error=login_required&error_description=Login+required&state=0dc4f29b-667a-4553-a11e-02aaffd05cf3) custom domains for JIRA Cloud in 2022. This, paired with a recent change in integration logic will pose problems. This epic aims to clean up our database and improve integration logic for this upcoming feature.
