skvlad 1d3c7e0b16 Move MetricsObserverInterface out of peerconnectioninterface.h
This change moves the definition of the UMA MetricsObserverInterface from api/peerconnectioninterface.h into api/umametrics.h. This allows us to remove the unwanted dependency on peerconnectioninterface.h from files in webrtc/p2p.

This is a simple refactoring with no functional changes.

BUG=None
