Implement production checks for post-deploy migrations
What does this MR do?
Implement production checks for post-deploy migrations. One of the first steps of gitlab-com/gl-infra/delivery#2046 (closed)
These checks will be executed before the post-deployment migrations are triggered on gstg and gprd. The checks are similar to the ones executed before the production deployment, so this commit implements a promotion check interface that can be used in both classes.
