Add env variable to disable express logging

[quentinleclerc]

Hello,
I've been needing exactly your software but with a slight change so I figured I might as well upload it, if someone needs it.

I just added an environment variable to disable express logging if not needed. I set it to true in the dockerfile to let the default behaviour unchanged.

Thanks,

I've redone the feature with a different environment variable, going in the opposite direction, I didn't want any extra variables required in the Dockerfile.

Also I've just removed the dashes completely, I don't think it served a good purpose.

I'll close this PR, this is now implemented here: #35

OK it's now in tag :23 and works by setting the environment variable, DISABLE_REQUEST_LOGS=true

AAAH I forgot your table! OK I'll add that another time it's a nice useful summary
