Title:
  integration tests: socket.error: Connection refused frequently happens
  in selenium remote driver

Status in OpenStack Dashboard (Horizon):
  Expired

Bug description:
  socket.error: [Errno 111] Connection refused frequently occurs recently in selenium remote_connection.
  This is seen in various tests. It seems selenium fails to connect a browser.

  For example, http://logs.openstack.org/14/303514/55/check/gate-
  horizon-dsvm-integration-current-ubuntu-
  xenial/af1bef2/console.html#_2016-09-21_10_56_45_019822

  66 hits in last 7 days in 311 integration test run (dsvm-integration-current and dsvm-integration-deprecated)
  The failure rate is 21%. The rate is high enough.

  logstash query:
  message:"socket.error: [Errno 111] Connection refused"
  AND filename:"console.html"
  AND (build_name:"gate-horizon-dsvm-integration-deprecated-ubuntu-xenial" OR build_name:"gate-horizon-dsvm-integration-current-ubuntu-xenial")
