Latest version of utils.py keystone issue on OSP7 (kilo)

[VIncent S. Cojot]

Hello,
I'm comparing the previous version of utils.py [1] to the current version of it [2]

/usr/bin/oschecks-check_keystone_api --os-username sensu --os-password sensu --os-tenant-name monitoring --os-auth-url http://10.153.20.2:5000/v2.0

*) With version [1] on OSP7, I get this result:
-------------------------------- CUT HERE ----------------------------------------------
OK: Got a token, Keystone API is working.|response_time=0.0941200256348
-------------------------------- CUT HERE ----------------------------------------------

*) With version [2] on OSP7, I get this result:
