    Clear volumes stuck in 'downloading'

    If the CinderVolume service is restarted while an image-copy is
    happening, the volume gets left in a 'downloading' state and
    cannot be used or deleted. This fix adds code to init_host to
    look for volumes (on this host) in such a state, and move them
    to an error state. It also calls clear_download in the driver
    in case the driver needs to perform an action, such as
    detaching the volume.

    Fixes Bug #1172645
