[Doc] Cluster-level failover shouldn't be part of Java client chapter

What issue do you find in Pulsar docs?

When I read the Java client document, I found a very long chapter to introduce cluster-level failover. Seems that cluster-level failover is a feature of Pulsar rather than the Java client, so I think this part needs to be moved to another place.

What is your suggestion?

I think we should move the introduction of cluster-level failover to the next chapter of Geo Replication, and just give code snippets in client library pages (if supported).

though, this feature is only available in Java client for now, see client feature matrix: https://docs.google.com/spreadsheets/d/1YHYTkIXR8-Ql103u-IMI18TXLlGStK8uJjDsOOA0T20/edit#gid=1784579914

Thanks for pointing out that, but I think moving the chapter is better. Reasons:

1. Cluster-level failover is a concept based on Geo replacation rather than a feature of the client.
2. Advanced features shouldn’t be at the beginning of documentation.

We can emphasize this feature is only ready for the Java client yet, and add usage examples at the end of the Java client doc.

@momo-jun > I think you can go ahead. The IA redesign is a long-term project with continuous improvements. I agree the overall IA work is a long-term project, but as we touch any content we should apply the best practices so we can make incremental improvements in keeping with the overall strategy.
