    Deprecate CONF.fixed_range, do dynamic setup
    
    Do dynamic fixed_range setup by pulling the networks that should
    exist on the host and making the appropriate calls to set up the NAT
    entries for each network. This allows for non-contiguous subnets to
    be configured in the fixed_ip space and only configures the NAT rules
    as they are needed. This also restricts the NAT range to the smallest
    range required preventing the NAT from impacting subnets that might
    exist on the external network.
    
    DocImpact: For backwards compatibility, Grizzly will still support
    the CONF.fixed_range option and if set will perform the default logic
    from Folsom and earlier releases. To use the new dynamic fixed_range
    setup in Grizzly, set fixed_range='' in your nova.conf. The intention
    is to remove the CONF.fixed_range option entirely early in the Havana
    cycle and use the dynamic fixed_range setup from Havana going
    forward.
