From the code, ReadOnly seems to work fine. I'll add tests later. |

During my testing, I confirmed through the cluster logs that the ReadOnly option takes effect. However, the ClusterClient does not provide a corresponding API, so I couldn't write a test for it. Can I add a public API for test? Or do you have any idea? @ndyakov |

Currently, when users use failover mode and want to implement read-write splitting, a close alternative is to use NewFailoverClusterClient with RouteRandom=true, but this is not the best solution.
Two simple solutions:
When using NewFailoverClient(), ReplicaOnly=true means allowing all commands to be routed to replicas.
When using NewFailoverClusterClient(), ReplicaOnly behaves the same as ClusterOption.ReadOnly.
@ndyakov @htemelski-redis @elena-kolevska Which solution do you think is better, or do you have another alternative?
