Title:
  SSH Auth fails in AdvancedNetworkOps scenario

Status in neutron:
  New
Status in OpenStack Compute (nova):
  New

Bug description:
  Affects all neutron full jobs and check-grenade-dsvm-partial-ncpu
  The latter runs nova network.

  In the past 7 days:
  105 hits (12 in gate)
  grenade: 30
  neutron-standard: 1
  neutron-full: 74

  in the past 36 hours:
  72 hits (8 in gate)
  grenade: 0
  neutron-standard: 1
  neutron-full: 71

  Something apparently has fixed the issue in the grenade test but
  screwed the neutron tests.

  Logstash query (from console, as there is no clue in logs) available
  at [1]

  
  The issue manifests as a failure to authenticate to the server (SSH server responds).
  then paramiko starts returning errors like [2], until the timeout expires
