Rework the module to log every request as a separate log entry

Problem/Motivation

The overall idea of the module is cool, but I have a vision of how to make the implementation of the module better:

1. Get rid of the dblog dependency, to allow using this module with any logger type - rework use just the EventSubscriber, instead of overwriting the whole logger.
2. Add more details about the response: response code, body size, duration, memory usage, etc.
3. Make including large data sections (such as headers) optional.
4. Add an option to log every request, not only requests with other logs - this will be very useful for profiling, especially together with the request duration and memory usage data.
5. Add support for passing the response details as structured metadata, to use with structured logging modules like Logger, OpenTelemetry, Extended Logger, etc.
6. Implement more cool things.

These will be breaking changes, so I want to release a 3.0 major version of this module, which will be a deep rework of the 2.x version.

And I am ready to implement all this from my side, and become a maintainer of the 3.x version of the module.
