getNodeIpForRequestedIpStack
	// We need to collect IP address of a matching IP stack for every node that is part of the
	// cluster. We need to account for a scenario where Node.Status.Addresses list is incomplete
	// and use different source of the address.
	//
	// We will use here the following sources:
	//   1) Node.Status.Addresses list
	//   2) Node annotation "k8s.ovn.org/host-cidrs" in combination with Machine Networks
	//   3) Deprecated node annotation "k8s.ovn.org/host-addresses" in combination with Machine Networks
	//
	// If none of those returns a conclusive result, we don't return an IP for this node. This is
	// not a desired outcome, but can be extended in the future if desired.

    1. Deploy vsphere IPv4 cluster
    2. Convert to Dualstack IPv4/IPv6
    3. Add machine network and IPv6 apiServerInternalIPs and ingressIPs
    4. Check keepalived.conf
