Removing InDetPerformanceRTT as it has been superseded by InDetPhysValMonitoring
InDetPerformanceRTT isn't supported anymore and the InDetPerfRTT test in ART have been crashing for a year by now in master. I think it is little point to have the package remaining anymore. Please feel free to object if there is any reason to keep it. At the point IDPVM should be validated sufficiently.
