Currently, we assume that ctlplane network configuration for RHEL9.4 installation uses 1 NIC at the time of definition in OpenStackDataPlaneNodeSet CR.
However, there is no description of this hidden assumption and there is no description to configure a custom NIC configuration for ctlplane.

If a user wrote a network configuration for ctlplane at edpm_network_config_template with bonding, there is a chance of network access issue while os-net-config configures the bonding for ctlplane.

To avoid the issue, we should have the description for networkData when a user wants to configure custom network configuration for ctlplane.
