feat: impletment discovery service by zookeeper
What this PR does: Implement the discovery service by Zookeeper.
Which issue(s) this PR fixes:
Fixes #580
Special notes for your reviewer:
I use the GetW function to monitor changes in Zookeeper nodes. When a node at the corresponding path changes, the corresponding operation is performed. I have written unit tests and have also verified the ZK registration and listening logic in incubator-seata-go-samples. By simply modifying the seatago.yml file and replacing the registry center with Zookeeper, TM and RM will be able to retrieve the TC's address. Below is the ZK configuration in seatago.yml.
# Registration Center registry: type: zk file: name: file zk: server-addr: 127.0.0.1:2181 session-timeout: 6000 connect-timeout: # not used username: "" # not used password: "" # not used node-path: /registry-seata/default
