Improve CinderFixtureNewAttachFlow
This does three things: 1. Implements the attachment_complete method in order to fail if code is trying to complete an attachment that does not exist. 2. Adds logging in the various attachment CRUD methods to aid in debugging test failures. 3. Mirrors the method signature for is_microversion_supported to make sure code is at least calling it properly.
