Comment 6 for bug 1680122

@Ghanshyam, yeah, I know it's better to use dynamic credential. But the reason why I still use actual credential is that I run the tempest test in a public cloud env. In this env, it's impossible for me to let tempest create/delete keystone user/project automatically.

For this bug, I don't want to fix it at Cinder side, because it may change API behavior, so we need a micro version bump. Then I'm not sure if tempest support to test with microversion, can it?

For the tempest patch, Thanks for your review. I'll take a look and update later.
