12.1 Factor Apps: Logs

The 12 factor app states that applications should log to standard out and standard error, thus not concerting themselves with the storage and processing of their log stream. That's a good start point, but we need more than that. The 12.1 factor app does these three things:

1. Supports a LOG_LEVEL configuration option
2. Uses a machine readable format, such as JSON, in production
3. Treats log streams as a telemetry source
