avf: add avf flow framework
This patch adds the flow support to VPP avf_plugin. Currently only IP4-N-TUPLE and GTPU flow are supported as a reference. More flows will be added later. Type: feature Signed-off-by: Chenmin Sun <chenmin.sun@intel.com> Change-Id: I563dbfacecd3eba31e8c3c7769142ea6adba54b6
