DOC-5665 Jedis failover docs

All feedback welcome on this rather complicated page, including:

• Is it too long? Maybe some of the content could be moved elsewhere.
• Do the diagrams make sense?
• Is the basic breakdown of presentation OK?

LGTM. Answers to your questions:

• Is it too long? Maybe some of the content could be moved elsewhere. [DWD] I think it's good that it's all grouped together; not obvious how you could split this up.
• Do the diagrams make sense? [DWD] Yes.
• Is the basic breakdown of presentation OK? [DWD] Yes.

Thanks @dwdougherty ! As regards splitting it up, I was wondering if we should have a page for the concepts, a bit like we do for client-side caching. Might make more sense to wait until some of the other clients support failover before doing that, though.

Ah... it wasn't clear to me that other clients would support this functionality. If that's the case, then maybe splitting the content into concepts and per-client implementation sections would probably make sense. Though, I think you're right about keeping it intact until other clients add support.
