Currently there are validation checks for platform None in OptionalInstallConfig that limits the None platform to 1 control plane replica, 0 compute replicas, and the NetworkType to OVNKubernetes.
These validation should be removed so that the None platform can be installed on clusters of any configuration.
- SNO cluster should still continue to work.
- SNO validation should still check only OVNKubernetes network type is allowed
- A compact or HA cluster can be installed with platform None, given the user has configured and deployed an external load balancer.
