flow: code refactor
This is the code refactor for vnet/flow infra and the dpdk_plugin flow implementation. The main works of the refactor are: 1. Added two base flow type: VNET_FLOW_TYPE_IP4 and VNET_FLOW_TYPE_IP6 as the base the flow type 2. All the other flows are derived from the base flow types 3. Removed some flow types that are not currently supported by the hardware, and VPP won't leverage them either: IP4_GTPU_IP4, IP4_GTPU_IP6, IP6_GTPC, IP6_GTPU, IP6_GTPU_IP4, IP6_GTPU_IP6 4. Re-implemented the vnet/flow cli as well as the dpdk_plugin implementation 5. refine cli prompt 6. refine display info in command "show flow entry" Type: refactor Signed-off-by: Chenmin Sun <chenmin.sun@intel.com> Change-Id: Ica5e61c5881adc73b28335fd83e36ec1cb420c96
