Remove documentation for the ovncontroller-config-dcn ConfigMap, ovn-dcn DataPlaneService, and instructions to replace the ovn service with ovn-dcn in DCN nodesets. The adoption should work without these extra steps.

The standard OVN service uses DNS (ovsdbserver-sb.openstack.svc) which resolves to internalapi IPs via DNSData CRs and should work for DCN nodes when proper inter-site routes are configured.

I have one very minor edit.

* Central site nodes reference `subnet1` for all networks.

. Create an `OpenStackDataPlaneNodeSet` CR for DCN1 edge site compute nodes. You must add inter-site routes to the network configuration template and use the `ovn-dcn` service:

Thanks @klgill I made that change.
