Jet Chiang 4b12ce67b0 ateapi: Support Postgres as alternative persistence backend (#640)
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:

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
