Description

The MetricGroup interface is currently overloaded, being used both for registering groups/metrics (typically called from user-functions) and accessing scope information (typically called from reporters).

Due to effectively having 2 different audiences with different use-cases it makes sense to move the scope-related methods into a separate interface.

This should make it a lot easier to extend these interfaces, as significantly less tests have to be adjusted.
