ofproto: Add NXM_NX_TUN_GBP_ID and NXM_NX_TUN_GBP_FLAGS

Browse Source 
Introduces two new NXMs to represent VXLAN-GBP [0] fields.

  actions=load:0x10->NXM_NX_TUN_GBP_ID[],NORMAL
  tun_gbp_id=0x10,actions=drop

This enables existing VXLAN tunnels to carry security label
information such as a SELinux context to other network peers.

The values are carried to/from the datapath using the attribute
OVS_TUNNEL_KEY_ATTR_VXLAN_OPTS.
