Charlton Austin fc4b3642d3 refactor(endpoints/api/tag): refactor code for v22
this decouples the database models from the api

[TESTING->locally with docker compose]

Issue: https://coreosdev.atlassian.net/browse/QUAY-632

- [ ] It works!
- [ ] Comments provide sufficient explanations for the next contributor
- [ ] Tests cover changes and corner cases
- [ ] Follows Quay syntax patterns and format
