`static NacosClientProperties`	`PROTOTYPE` all the NacosClientProperties object must be created by PROTOTYPE, so child NacosClientProperties can read properties from the PROTOTYPE. it looks like this: \|-PROTOTYPE----------------> ip=127.0.0.1 \|---\|-child1---------------> port=6379 if you search key called "port" from child1, certainly you will get 6379 if you search key called "ip" from child1, you will get 127.0.0.1. because the child can read properties from parent NacosClientProperties
