Remove remaining usage of cinder v1 API call from Tempest

Cinder v1 API tests have been removed from Tempest
- I04de2d90fe11f8ec4acbfa983bc0ad3aa979f45b

There are few other tests like compute, scenario which makes
call to Cinder v1 API based on api_v1 is configured.
We should cleanup those to go with v2 directly and later
those will be directed to make v2/v3 APIs.
