Jasvinder Singh c1656328db meter: replace color definitions
This patch implements the changes proposed in the deprecation
note[1]. Replace multiple color definitions in various places such as
rte_meter.h, rte_tm.h and rte_mtr.h with single rte_color defined
in rte_meter.h.

This is simple search and replace exercise without any implementation
change.
