Create audit log of deployment override checks in release issue
To create a complete audit log of our deployment decisions we need to capture the On Call Engineer's approval for overriding deployment checks. Currently approval is requested and granted only in Slack which means we don't have a long-term record.
As a first iteration to fix this, Release Managers will continue to ask the On Call Engineer for approval to override deployment checks via Slack. Once the deployment begins and has been recorded on the release issue e.g the Release Manager will share a GitLab comment link and ask the On Call Engineer to record their approval as a comment reply.
As a second iteration, Delivery will follow up with a less-manual approval approach. Details to follow.
