   @AlbumenJ Not sure if anyone is working on this issue, so want to try implementing this one.
   
   My implementation:
   1. Add an enum `FallbackPolicy`, which contains `RANDOM`, `EXCEPTION`. `RANDOM` will be the default policy to ensure that the existing logic is not changed.
   2. Add `fallbackPolicy` as a field to [DubboRoute](https://github.com/apache/dubbo/blob/3.2/dubbo-cluster/src/main/java/org/apache/dubbo/rpc/cluster/router/mesh/rule/virtualservice/DubboRoute.java).
   3. Extend the original fallback logic: https://github.com/apache/dubbo/blob/3.2/dubbo-cluster/src/main/java/org/apache/dubbo/rpc/cluster/router/mesh/route/MeshRuleRouter.java#LL216C1-L222C10
   
   Please let me know if you have any suggestions.
