> TracingUtil.createProxy is a helper method to create a proxy instance with
> tracing support.
> The proxy instance implements the same interface as the original class and
> delegates all the method calls to the original instance but it also sends
> tracing information to the tracing server.
> By default it's not a big overhead as the tracing libraries can be configured
> to send tracing only with some low probability.
> But to make it more safe we can make it optional. With a global
> 'hdds.tracing.enabled' configuration variable (can be true by default) we can
> adjust the behavior of TracingUtil.createProxy.
> If the tracing is disabled the TracingUtil.createProxy should return with the
> 'delegate' parameter instead of a proxy.
