* [FIX] update documentation
- add `PYTHONDONTWRITEBYTECODE` environment variable
- rename pip package `psycopg2-binary` to `psycopg2`
- add db environment variables in docker-compose for a better usage
- use `os.environment` in `setting.py` to get environment variables
* [fix] update documentation
BuildKit allows using alternative Dockerfile syntaxes to introduce new features
without having to update Docker itself. The general recommendation is to always
specify a "syntax" directive in a Dockerfile, so that (if needed) older versions
of Docker can download the correct syntax to build the Dockerfile.
This updates our examples to include a syntax directive, to make users more familiar
with these directives, and to illustrate best-pracitces in our documentation.

Unifying all "examples" in this directory; some of these should still be
reviewed and/or removed in favor of examples from "awesome compose"
