Reduce number of (debug) log events

[njam]

Currently 50'000 events per hour => ~14 events per second.

Ideas:

• Combine debug records for the same transaction over some time? (instead of "-> browser", "-> janus" etc all separate?)
• What else?

[njam]

As discussed with Tomasz earlier: Let's change the log verbosity to INFO on production, and make sure that it contains all relevant logs. Then for development we can keep DEBUG which might be useful.

Can you do the necessary changes?

[vogdb]

ok

[njam]

DEBUG: Combine messages that come from browser and go to janus.

INFO:

• connection pair: connect, disconnect
• session: create, destroy
• plugin: attach, detach
• stream: create, stop

WARN: Errors on external services

ERROR: Unexpected internal and external errors

FATAL: Uncaught errors

Please merge upstream. Maybe make sense to redo the pr.

@tomaszdurka please review. Please pay attention to how I moved logging from lib/connection.js to lib/proxy.js
