Add rate limiting for logging

**Feature request**
It would be great to have monitoring for parsers.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_monitoring` with default `false`.

The issue does not name files, tests, or entry points. Start by locating the parser monitoring and logging configuration entry points, then clarify whether the intended result is rate limiting for logging, parser monitoring, or both; done should include the agreed behavior for enable_monitoring and its default false setting.
