Cleanup logging

[olevski]

Currently we log random things via random logging libraries. We should use just one and ensure that it works properly. The biggest problem here is that alembic does weird things with the logging.

I would prefer we used the python logging library everywhere.

For logging in requests we should use and print the request id from the header (from the gateway) in every request. That way we con search for all logs related to a single request. Which is useful.

Also it would be nice if we can control the verbosity. But we just need a normal/prod level and a debug level. We dont need more categories.
