Extends the CandidateAverageMetric with Auth Entry

This adds the auth entries response collective into the candidate
average metric, thereby creating a full aggregate for the response
information. It also sets up the Get emit logic, and is a step towards
final completion of the collection system.

The threaded timed get emit system was removed in favor of an immediate
function-based buffer/queue logging system that will be added once all
changes are in.
