    Fix for qemu-nbd hang

    NBD device once used seem to run into intermittent trouble when
    used with mount repeatedly. Adding code to explicitly flush the
    device buffers using 'blockdev --flushbufs'.

    NOTE(dmllr): Also merged regression fix:

        Consolidate the blockdev related filters

        Seeing a "/usr/local/bin/nova-rootwrap: Unauthorized command" error
        in the logs when "blockdev --flushbufs" is executed because of the
        existing blockdev in compute.filters. We need to merge both into a
        single RegExpFilter
