PP-483: PP-484: PP-485: Enhance output of qstat to make it more admin and script friendly

                  Special case (when user variables contains special characters):  

            All the three new interfaces will be supported only with full set of attributes (" -f " option). This would include every vaild combination of "-f" (Ex: "qstat -Qf" or "qstat -Bf")

            Using it with other optargs will throw the already existing "conflicting options" error and prints the usage on the screen.
