Centralise logging

Summary:
Centralise connectivity logging into a single place. By having all logs go through a single interface, then it becomes trivial to manipulate them as needed.

In this change, this is not done.

In subsequent diffs, logs will be dispatched via an event and will be visualised in the Connectivity Hub.
