Description

Does st2.conf file support adding redundant pairs of backend coordinator like zookeeper or redis? We have zookeeper cluster (3 instances) but not sure how to include 3 instances in st2.conf. Tried below config but doesn't work.

[coordination] url = kazoo://user:pass@host1:2181/, kazoo://user:pass@host2:2181/, kazoo://user:pass@host3:2181/

Research direction
Examine the st2 configuration parsing in `st2common/config.py` for the `[coordination]` section. Check the Kazoo library documentation for the correct URL format for multiple ZooKeeper hosts. The issue suggests a comma separated format which may not be supported; verify if a different delimiter or multiple `url` entries are needed. Update the official documentation to clarify how to list multiple ZooKeeper instances.
