    Added need info to accept_transfer

    Drivers that implement accept_transfer will need
    things like the new user_id and project_id. We were
    not including this in the original add, in order for
    drivers that are tenant aware this information will be
    necessary.

    Also the get_volume call in the transfer was using
    the new user context, so the volume would never be
    found. We fix this here by providing an elevated
    context to the get_volume call when accepting the
    transfer.
