You could use this in your PE tests in case  you need to see the difference between multiple
seeks done by the same client. JFYI. Thanks.

> Currently in PE tool all the scans and gets adds explicitly the columns to be scanned.
 The tool by default adds only one Qualifier.  Doing this addColumns leads to Explicit Column
Tracker which does seeks frequently. If we want to know a simple scan performance as a basic
scenario then we should have the option to add this columns explicitly.
