    Refuse to block migrate instances with config drive

    libvirt does not block migrate read only devices such as config
    drives. It decides that the config drive is read only because it
    is attached as a cdrom. So, we just throw our hands up in the
    air and bravely refuse to block migrate those instances.

    DocImpact: you should read all that stuff above.

    Note that block migration hates readonly things

    As noted in the DocImpact, block migration + config drive
    does not work. This patch adds a mention so that reader
    is aware while selecting.
