Add region name to OpenStack credentials
Currently functest doesn't account for regions when it tries to instantieate OpenStack clients. As a result, the code fails when functest is used in a multi-region environment. The fix forces functest account for region name. Signed-off-by: Dimitri Mazmanov <dimitri.mazmanov@ericsson.com> Change-Id: Iebbd20042548c02da9d5ed7e58a454347a555778
