Public bug reported:

during the kilo development cycle

a new vif type VIF_TYPE_VHOST_USER was added to the nova libvit driver.

in parallel a ovs dpdk mechanism driver was also created which consumes
this new VIF type.

as humans are error prone when multitasking i forgot to introduce the pathset to add 
vhost_user constants for port binding to 
https://github.com/openstack/neutron/blob/master/neutron/extensions/portbindings.py

the rfe bug captures the addtion of the following binding constants for
the vhost user interface.

#  - vhost_user_ovs_plug: Boolean used to inform Nova that the ovs plug
#                         method should be used when binding the
#                         vhost user vif.
VHOST_USER_OVS_PLUG = 'vhostuser_ovs_plug'

#  - vhost_user_mode: String value used to declare how the mode of a
#                     vhost-user socket
VHOST_USER_MODE = 'vhostuser_mode'
#  - server: socket created by hypervisor
VHOST_USER_MODE_SERVER = 'server'
#  - client: socket created by vswitch
VHOST_USER_MODE_CLIENT = 'client'

#  - vhostuser_socket String value used to declare the vhostuser socket name
VHOST_USER_SOCKET = 'vhostuser_socket'

#  - vif_type_vhost_user: vif type to enable use of the qemu vhost-user vif
VIF_TYPE_VHOST_USER = 'vhostuser'

# default location for vhostuser sockets
VHOSTUSER_SOCKET_DIR = '/var/run/openvswitch'
