samples: pktgen: new append mode
To configure various complex flows we for sure can create custom
pktgen init scripts, but sometimes thats not that easy.
New "-a" (append) option in all the existing sample scripts allows
to append more "devices" into pktgen threads.
The most straightforward usecases for that are:
- using multiple devices. We have to generate full linerate on
all physical functions (ports) of our multiport device.
- pushing multiple flows (with different packet options)
