Specify log level with Node environment variable

See original GitHub issue

With NODE_DEBUG it’s possible to specify logger names which should be active. Is there also a setting to specify the log level?

For example, I would like to see only logs from “foo” which have log level “warning” or “error” but no “debug”, “info” and/or “log”.

I would like to set something like:

NODE_DEBUG=foo NODE_DEBUG_LEVEL=error,warn node example/node.js
