[v5,1/1] app/testpmd: support different input color method

  From: Sunil Kumar Kori <skori@marvell.com>

To enable input coloring, based on VLAN or DSCP, patch adds
command line interface to configure the following:

 - configuring input coloring using VLAN or DSCP while creating
   meter i.e. during rte_mtr_create()

 - Update VLAN input coloring table at runtime.

 - configures protocol priorities.

 - retrieve protocol and priority information

Depends-on: patch-22751 ("ethdev: mtr: support protocol based input color selection")

v4..v5:
 - Update testpmd user guide.

v3..v4:
 - Replace strcmp with strcasecmp whereever is needed.
 
v2..v3:
 - Rebased to branch ToT dpdk-next-net/main
 - Fix static keyword for newly added token parsing symbols

v1..v2:
 - Rebased to branch dpdk-next-net
 - add CLIs for input coloring mechanism
