    DVR: Agent side change for live migration with floatingip

    During live migration when an instance is in a pre-migration
    state, and if the fixed_ip of the port has an associated
    floatingip, the floatingip namespace should be created in
    the destination node, before the VM instance lands on the
    node.

    The server side code will handle the pre-live migration case
    and initiate the router creation on the destination node and
    also will provide the 'dest_host' as an additional attribute to
    the floatingips dictionary that is being passed to the agent.

    So this patch reads the 'dest_host' and the 'host' variable
    and if any of the two matches with the host, it will allow
    the floatingip to be processed.

    This will be an agent side change for addressing the vm
    migration with Floatingip enabled.
