Problem

--logging=DEBUG level is too spammy for end users and either we have to use the ADMIN RPC endpoint to target packages/classes or get them to post full logs which is a barrier and error prone.

Goal

End users can enable --logging=DEBUG and have a chance at spotting an issue or pasting relevant snippets into support channels.

DEBUG Principles

•  Aimed at both end users and developers
•  Should lead to resolution of common problems, whilst not spamming
•  Should not contain logs that take up more than one terminal screen, e.g. raw data, including RLP

DEBUG Guidelines

• Should not include peer discovery
• Should not include txpool management
• Could include some peering to debug peering issues
• Could include some high level syncing
• Could include API requests, including potentially truncated data, but not full RLP

TRACE principles

• Aimed at developers
• Expectation is everything is there and it's spammy
• Only useful when targetting certain packages/classes

Actions (if no objections)

• Submit PR(s) to move logs from DEBUG → TRACE and any other tidy up to follow the proposal
• Update existing documentation, e.g Coding Conventions and Logging
