CC-2137 NZSL move Signbank to poetry (#171)

##JIRA Ticket

[CC-2137 NZSL: move signbank to
Poetry](https://ackama.atlassian.net/browse/CC-2137)

## Changes

- `requirements.*` files removed
- `pyproject.toml` and `poetry.lock` added
- unpinned all dependencies
- added `depends_on` and `healthcheck` to `docker-compose.yml` to avoid
database race condition on local dev
- exposed port `5432` on local dev
- `0.0.0.0` added to `DEFAULT_ALLOWED_HOSTS`
