Cluster manager shouldn't error out on localnets with no subnet

Localnets without a subnet specified are perfectly valid, but cluster manager will keep erroring out because of len(nInfo.Subnets()) > 0. This produces a red herring in the logs, where we retry to create a secondaryNetworkClusterManager 15 times until we give up:

I0724 18:43:21.377878      16 controller.go:257] Controller [clustermanager-nad-controller network controller]: error found while processing gh25b_tenant-blue: [clustermanager-nad-controller network controller]: failed to ensure network gh25b_tenant-blue: failed to create network gh25b_tenant-blue: no cluster network controller to manage topology

Let's not consider this an error when ensuring a network.
