Elza Mathew a4fd5eeead app/testpmd: refine xstats show 
When using "show port xstats all" command to show xstats, the output
is usually too long to obtain what you really want, especially when
multi-queue is enabled.

Added an option to set whether zero values should be displayed
or not for xstats. The "set xstats-hide-zero on|off" command enables
the user to decide if the zero values should be shown while
displaying xstats.
