Enable gunicorn debug log

[gloriousDan]

While helping to debug some gunicorn startup issues I realized that the gunicorn log level was not yet configurable. So I modified the .env file and boot.sh script to make the gunicorn loglevel configurable by setting the GUNICORN_LOG_LEVEL variable.

We could maybe also use the DEBUG variable to modify the gunicorn log level as well I'm open to both possibilities.

thanks for the PR, have you tested this with the container?

I think having it as an extra variable makes sense but maybe we place it next to the other debug variables in the .env template?

i really need to wirte a proper docs article about all the environment variables and its considerations ...

I tested it and with the default setting it indeed behaves as before. With "debug" additional info is printed by gunicorn. I szill have to test what happens when a invalid value is set and how if the other settings work. I also built the docker image (wirthout node though) under: gloriousdan/recipes-debug

But I'll do some further testing and move the env variable to the section at the start and then get back to you.

Thanks, this sounds tested enough to me :)

I now tested it with an invalid value and gunicorn starts just fine with the default logging value. I also moved the env variable to the top of the env file and added some more info about it.
