Adds a Quickly Designed Logging Setup

A new object is generated that mimics the proto object, but allows us to
hold state better (CandidateProviderMetrics and ChosenProviderMetrics).

Then within our calls, at designated locations in the query and final
phase, we set these objects to have certain values. This occurs in base
classes, such as ProviderSession, or in specific parts of RequestSession
where it makes most sense.

Finally, in all existing logging methods, a way to retrieve the data is
used. To avoid issues with slow or expired requests coming back, the
iteration is protected so that the log occurs for what is obtained at
the moment (synchronized...() methods don't prevent iteration issues).
