feat(forknet) - configure log config only in new_test

[wacban]

My goal is to figure out how to set the log level in forknet. Please consider this PR only as an RFC for what would be the best approach to solve this problem. I think in the perfect world the initial setup would happen only once e.g. in new_test or in reset. It may also be nice to add a command to adjust the log config but this can always be done with run-cmd so it's low pri.

I also refactored things a bit, sorry for mixing it with the real change. The real change is moving configure_log_config from start_neard to new_test, the rest should be a noop.

I am going on PTO for a week so feel free to take over this PR if it's needed. If not I'll finish it up when I'm back.
