Adds Postgres as an alternative persistence backend for ateapi as proposed in #731. Currently this is opt-in with flags in ateapi or use the `--store-backend=postgres` option in the install script. Slack discussion: https://cloud-native.slack.com/archives/C0B6M3E2J3D/p1785183769252679 Performance benchmark results for Postgres vs Redis: https://docs.google.com/document/d/12-ko_BFHcBo_nJkx9f4B7zMbiiWKC2saGhMhZG3aQ-s/edit?usp=sharing Benchmarks are not included in this PR, but you can reproduce the results by following the doc above Limitations and questions: - This draft does not yet handle migrations, this might come as a follow up - It currently uses `testcontainers` for testing Postgres, but as a result it adds a lot of dependencies --------- Signed-off-by: Jet Chiang <pokyuen.jetchiang-ext@solo.io>
