Comment 6 for bug 1835186

yes, url used in Tempest is wrong. i cannot find such API in cinder.

This is used in below test and we need to investigate why it is working and not giving error. May be 'provider' string is taken as id by cinder API but at some stage it should return error as this is unknown id.
