 * consider using registerTraceStartHook, registerTraceEndHook to order them properly.
 * To properly trace monitored function the TraceStartHook hook must be the first preInvocation hook in the app.
 * Correspondingly the TraceEndHook must be the last postInvocation hook in the app.

 * Otherwise, it doesn't return a tracer provider and the components must be configured manually or by calling configureDynatrace(). Default: false.
