    RemoteFS: prevent creation of encrypted volumes

    Support for volume encryption of FS-based volumes is not
    currently implemented in Nova. Creating encrypted volumes
    with these drivers can result in dangerous and undesired
    behavior. Block creation of encrypted volumes for these
    drivers until this is supported.

    This adds a per-driver switch which can be used to enable
    this for individual RemoteFS drivers as they are tested.
