[dpdk-dev] [PATCH] app/testpmd: support meter color action in policy

[Haifei Luo <haifeil@nvidia.com>]

Currently action RTE_FLOW_ACTION_TYPE_METER_COLOR is defined.
Add the CLI for this action in meter policy: color type (types)
There are three types: green, yellow and red.

Example for the new policy meter CLIs:
   add port meter policy 0 1 g_actions color type green / end y_actions
     color type yellow / end r_actions color type red / end

In the above command, the action type is RTE_FLOW_ACTION_TYPE_METER_COLOR,
the meter policy action list: green -> green, yellow -> yellow, red -> red.
