functional test fails on parsing output

[Jeremy Liu]

Currently, I'm running functional test for barbicanclient and get error on some testcases. The captured output is as below:

======================================================================
ERROR: functionaltests.cli.v1.smoke.test_acl.ACLTestCase.test_acl_submit_short_arg_true
----------------------------------------------------------------------
_StringException: Traceback (most recent call last):

sre_constants.error: nothing to repeat

Digging into the code in "python-barbicanclient/functionaltests/cli/v1/behaviors/base_behaviors.py", the regex for parsing output is not correctly written, and this seems to happen on some python versions. See https://bugs.python.org/issue18647
