    libvirt: Add announce-self post live-migration workaround

    NOTE(melwitt): This is the combination of two commits, the workaround
    config option and a followup change to add a note that enabling the
    workaround will cause the guest domain to be considered tainted by
    libvirt.

    This patch adds a workaround that can be enabled
    to send an announce_self QEMU monitor command
    post live-migration to send out RARP frames
    that was lost due to port binding or flows not
    being installed.

    Please note that this makes marks the domain
    in libvirt as tainted.

    See previous information about this issue in
    the [1] bug.

    This updates the announce self workaround config opt
    description to include info about instance being set
