What is the purpose of the change

fix issue: apache/dubbo#12763

most people depoy service in three zone for HA , we expect service rpc in same zone :

- 172.37.67.0/24 #zone=cn-shanghai-a
cn|shanghai|b:
- 172.37.68.0/24 #zone=cn-shanghai-b
cn|shanghai|c:
- 172.37.69.0/24 #zone=cn-shanghai-c

some company's service are in a big zone , we expect service rpc in same cell :

tag-subnets:

cn|shanghai|a|cell-1:
- 172.31.35.0/24 #zone=cn-shanghai-a
cn|shanghai|a|cell-2:

cn|shanghai|a|cell-3:
- 172.31.37.0/24 #zone=cn-shanghai-a

some company's service are in serveral city, we expect service prefer rpc in same zone , and rpc special service across zone( such as stock quantity service):

tag-subnets:

cn|shanghai|a:
- 172.37.66.0/24 #zone=cn-shanghai-a
cn|hangzhou|b:
- 172.37.67.0/24 #zone=cn-hangzhou-b
cn|shenzhen|c:
- 172.37.68.0/24 #zone=cn-shenzhen-c
"":
