Log: Improve readability

[iamandrii]

The Problem

Enabling Log Level debug prints out a lot of useless stuff, for example, event broker logs, leading to unreadable logs.

Expected

Logs should remain readable.

Proposed solution (1)

Add Log Level trace to make all of the useless logs to go there.

Proposed solution (2)

Enable log filtering, to filter-out messages from unnecessary modules (like event broker, it mostly always works well).
