    xen: mask passwords in volume connection_data dict

    The connection_data dict can have credentials in it, so we need to scrub
    those before putting the stringified dict into the StorageError message
    and raising that up and when logging the dict.

    Note that strutils.mask_password converts the dict to a string using
    six.text_type so we don't have to do that conversion first.
