Gate test is masking failure details

[Paul Michali]

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

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.

I think that's the behavior of the testr, but that's what needs to be verified.
I doubt we can do anything in neutron to address this
