[ENHANCEMENT] support structured logging

axiomofjoy commented 7 months ago

Phoenix is no longer just a library, but is also a containerized application. We should update our logging accordingly.

[ ] Add a setting that can be configured by an environment variable that will configure structured logs for Phoenix. By default, no non-standard logging configuration will be used so that Phoenix continues to act as usual when used as a library (e.g., in a notebook environment).
[ ] Add a JSON formatter.
[ ] Log off the main thread with QueueHandler.
[ ] Use UTC timestamps.

Unscheduling this one and closing the PR for now. We can revisit when it becomes relevant.

Closing for now, I can revive the PR if it becomes necessary.
