While working on MDL-76055, it was not easy to enable MNet built-in debugging, neither it was really useful, many times showing encrypted information instead of the practical (unencrypted) requests and responses.

Also, there isn't any setting to enable that debugging, it must be done manually.

So this issue is about to:

• See how MNet debugging can be done to work better with standard Moodle debugging settings.
• See how we can improve MNet debugging/logging to show information that is more useful to the developer tracing problems.
