/**
* <P>This package contains wrapper logic for the CQL driver to allow more
* detailed diagnostic data to be captured. Because the Driver "v4" tries
* to protect developers from themselves and nearly disallows extension,
* lots of boilerplate had to be added to implement a wrapper.</p>
*
* <p>The purpose of this code is to see basic details from the load balancer's behavior.
* The operative part of this package is simply
* {@link io.nosqlbench.adapter.cqld4.wrapper.Cqld4LoadBalancerObserver},
* which intercepts query plan logic and logs details at a configurable level of details.
* </P>
*
* TODO: adapt diag markers from http
* TODO: inline the diagnostic filters into op dispenser logic
* TODO: make load balancer diagnostics record scoreboard data isochronously to a separate file
