Another solution to cluster network segment conflict for clusterlink

[duanmengkk]

In situations where there are multiple Kubernetes clusters in existence, the cluster networks often conflict with each other. If a cross-cluster service needs to be deployed across multiple existing clusters, in the case of network segment conflicts, we can create a new ip pool that does not conflict. The pod-ip of the newly created pod will use the new ip pool address range, and the container networks between the new ip pools will be interconnected through clusterlink.
