    update nova-next and nova-ovs-hybrid-plug to disable linuxbridge
    
    neutron now declares linuxbridge experimental and requires
    it to be enabled by a new config option. We do not set
    that in these jobs so the neutron server fails to load
    since we enable the linux bridge mech driver.
    
    we do not actully use linuxbridge in these jobs so this patch
    just disables the mech driver.

Title:
  adapt ci to neutron making linux bridge experimental

Status in OpenStack Compute (nova):
  Fix Released
Status in os-vif:
  Fix Released

Bug description:
  tl;dr neutron now considers linuxbridge which uses to be the default mech driver in docs to be experimental and it is now guarded by a config flag.
  we do not set it in our jobs that have the mech driver loaded but not used so neutron fails to start.


  recently i noticed that gate jobs were failing with

  + functions-common:test_with_retry:2384    :   timeout 60 sh -c 'while ! wget  --no-proxy -q -O- http://10.209.98.53:19696; do sleep 0.5; done'
  + functions-common:test_with_retry:2385    :   die 2385 'Neutron did not start'

  
  dining into this a little more we see

  server[90491]: INFO neutron.plugins.ml2.managers [-] Configured

  server[90491]: ERROR neutron.common.experimental [-] Feature
  'linuxbridge' is experimental and has to be explicitly enabled in
  'cfg.CONF.experimental'

  the nova-ovs-hybrid-plug and nova-next jobs both enable the
  linuxbridge mech driver but don't actually use it since they only
  deploy ovs.

  https://github.com/openstack/neutron/commit/7f0413c84c4515cd2fae31d823613c4d7ea43110
  merged moving linux bridge to experimental

  so all jobs that have it enabled either need to remove it form the
  mech drivers list or enable it in the config via the new option.

  
  for nova-next and nova-ovs-hybrid-plug we can just remove the driver form the list for os-vif
  the os-vif-linuxbridge need to enable it via the new config option
