Dynamic logging lvl

[Exca-DK]

Issue

Currently, logging is only set at the bootstrap with the defined log level. It would be beneficial to have the capability to dynamically change that through RPC. Furthermore, for greater extendability, it would be valuable to make it configurable per module.

Rationale

Why should this feature exist? Enhanced debugging and observability. Often, managing nodes requires specific logging for a limited duration. Maintaining a low level for the entire node lifetime is unnecessary. Additionally, some loggers in the codebase have hardcoded lvl such as the one in DB.

What are the use cases? The feature would be particularly useful for debugging modules eg. enabling more verbose logs for the p2p module while keeping the rest of the loggers unchanged or temporarily lowering the global logging level.
