Comment 3 for bug 1509635

As of beta 15, we're seeing this message not just when destroying models, but also during controller bootstrap:

ERROR cmd supercommand.go:458 failed to initialize state: getting storage provider "cinder": volumes not supported: endpoint "volume" in region "RegionLXD" not found

Full output of `juju bootstrap` failure is attached.

Had to downgrade to beta 14, for now, to work around it.
