[Logger] Simplify how we instantiate the logger in plugins

[yoannmoinet]

What and why?

Logger requires the plugin itself to instantiate its logger, so it may do it with any name it wants.

We'd need to keep control over how we display logs from other plugins in the ecosystem.

How?

• Pass down an already instantiated logger to all the plugins.
• Allow plugins to create "sub-logger" if they need more granularity on what to log from sub systems.
• Enforce all plugins to export their PLUGIN_NAME (using yarn cli integrity).
• Add tests.
