Addresses backend/db review comments

- Fixes multiple typos on AutoDevops script
- Add an alias to Clusters::Cluster#domain as base_domain, so it's more
descriptive
- Removes unnecessary memoization on qa specs
- Changes migration to a post migration to deal better with traffic on
big instances (like gitlab.com)
