- Inform a cluster to remove a node from it:
`databend-meta --leave-id <node_id_to_remove> --leave-via <node_addr_1> <node_addr_2>...`
`databend-meta --leave-via` will try to remove the node and quit at once.
`--leave-via` specifies a list of the node `advertise` addresses to send the `leave` request to.
See: `--raft_advertise_host`
`--leave-id` specifies the node id to leave. It can be any id in a cluster.
- An CI of join/leave is added to ./tests/meta-cluster/
- Add doc `docs/doc/50-manage/00-metasrv/20-metasrv-add-remove-node.md` about how to remove a node from the cluster
Other refactoring:
- Remove # `MetaRaftError::JoinClusterFail`, use `MetaError::MetaServiceError` instead.
