DVR: run L3 output features
- rename l2_bridged to is_dvr. Including on the ip.api this was new in the 18.01 release so no compatability issues. - steal the free space in vnet_buffer_opaque_t for use with flags. - run the ipX-output feature arc from the DVR DPO Change-Id: I040e5976d1dbe076fcdda3a40a7804f56337ce3f Signed-off-by: Neale Ranns <nranns@cisco.com>
