    adds support for vhost user reconnect.
    
    - vhost-user reconnect is a new feature added
      in dpdk 16.07 and qemu 2.7.
    - vhost-user reconnect allows VMs using vhost-user
      interfaces to reconnect to the vhost-user backend if
      the backend terminates either as a result of a graceful
      shutdown or a crash with out requiring the vm to reboot.
    - vhost-user reconnect requires qemu to be the vhost-user server
      and ovs to be the client.
    - dpdk prior to 16.07 only supports qemu client/ dpdk server mode.
    - This change extends the ovs mech driver to select the correct qemu
      vhost user socket mode based on the available interface types
      reported by the agent.

Title:
  [RFE] add support for vhost-user reconnect to the ovs neutron agent

Status in neutron:
  Fix Released

Bug description:
  vhost-user reconnect is a new feature added in dpdk 16.07 and qemu 2.7

  vhost-user reconnect is a mechanism which allow a vhost-user frontend
  to reconnect to a vhost-user backend in the event the backend terminates.
  This enable a vm utilising a vhost-user interface to reconnect
  automatically to the backend e.g. a vswitch without requiring
  the vm to reboot.
