Move HA Config Snippet to Configuration Section

[josephaw1022]

What would you like to be documented:

All I simply am requesting is that this is moved (or copy) this section here

to the configuration page

Why is this needed:

• Make it easier for anyone to have a page that has details about specific configurations, but also has useful examples that the user can see on the same page

HA is a feature, not a config option. Adding nodes is a config option, which is already covered in the config docs (and the quick start).

The reason HA is mentioned in this page is to cover the airgapping requirements, the config example is to clarify what we mean by "HA".

What's your use case for "HA"? This feature is extremely niche and poorly supported currently.

The only reason I brought this issue up was is specifically because I noticed it in the offline section and thought that it would be an interesting thing to note under the mutli node cluster intro section.

As just a way to say "you can configure an ha cluster as well"

That's all that I was getting at
