feat: refine Logger implementation

[weboko]

Statement

Currently we have following format: waku:info:stream-manager:/vac/waku/metadata/1.0.0
It is limiting as:

• we already can filter level of log by using UI of dev tools;
• our interest is a feature scope and it is not possible to narrow down logs by configuring localStorage for now;

Proposal

Change implementation so that it is of following pattern: <app-name>:<feature>:<log-level>: method name / local feature: informational message.
