Heterogeneous multi-cluster full mesh communication practice

" summary

Describes building high-performance networking between heterogeneous Kubernetes clusters for big data workloads by using host routing at layer 2 and VXLAN tunnels at layer 3. Explains that mainstream CNIs support host routing, but when CNIs use different VXLAN VNIs they cannot form tunnels, so one CNI must be programmatically extended to align VNIs; Antrea is chosen as the core CNI because it supports configurable VNI.
