Title:
  Gate test is masking failure details

Status in neutron:
  Incomplete

Bug description:
  Both the 2.6 and 2.7 gate tests are failing, console log indicating
  two failures, but only showing one failure 'process-retcode'. When
  looking at testr_results it shows a fail and only mentions:

  ft1.12873:
  neutron.tests.unit.services.vpn.service_drivers.test_ipsec.TestValidatorSelection.test_reference_driver_used_StringException

  Here is 2.7 logs: http://logs.openstack.org/51/102351/4/check/gate-
  neutron-python27/a757b36/

  Upon future investigation, it was found that there was non-printable
  characters in an oslo file. With manual testing, it shows the error:

  $ python -m neutron.openstack.common.lockutils python -m unittest neutron.tests.unit.services.vpn.service_drivers.test_ipsec.TestValidatorSelection.test_reference_driver_used
  F

  A fix will be done for the oslo error, but we need to investigate why
  the gate test does not show any information on the error.
