Test utils refactoring:  * quantumclient import was wrapped to    handle situation when it is not installed    this case novaclient will be used  * cinderclient import was wrapped with ImportError    to handle situation when it is not installed    will be ommited this case.    Note: this wrapping allows run tests where    the client is not used. Previously all the    test run was interrubped on itinialization state
