Is allow_overlapping_ips config option still needed really?

[Slawek Kaplonski]

Help message of this option is saying that it "MUST be set to false when Neutron is used with Nova's security groups". But is it really still the case? I think it's not and we could maybe remove that option finally? Any opinions about it?

Nova-network was removed in ussuri (I think this was the topic: https://review.opendev.org/q/topic:%22bp%252Fremove-nova-network-ussuri%22+(status:open%20OR%20status:merged) ) so as I see we can remove it, perhaps with a deprecation for Yoga but as nova-network code is deleted since ussuri, I see no issue to remove it in xena.

    Deprecate 'allow_overlapping_ips' config option

    Config option allow_overlapping_ips is deprecated to removal now and
    will be removed in the Z cycle.
    Default value for that option is now set to True as this is supported by
    IPAM module in Neutron.
