Print OpenStack version in connection_check
Functest is becoming very used and sometimes vs older OpenStack
releases (ONAP Openlab). It will ease debugging and easily find
backward incompatibilities.
Even if that value could be checked for OPNFV Release Management,
testing older SUT is not considered as false from a Functest statepoint.
