Move verbose console behind settings flag

[joshbw]

The console.log right now is super verbose, which is helpful for debugging but not necessary for everyday users. The console.log should be behind a debug settings flag of some form, so it can be enabled selectively should a user want it

I'll add to that while the code is littered with console.log, which lead me to think the output would be super verbose, the actual implementation is in connection.ts, and is nothing but a noop - SOOO both implement logging and hide it behind a settings flag (maybe unify the rule/engine dev flags, with rules validation also there)
