docs: Document workaround to disable SNI checks

[lfrancke]

Description

Important

This should only be merged once stackabletech/docker-images#1225 is merged

Document workaround to disable SNI checks.
I took the opportunity to rewrite the entire FAQ entry.

[sbernauer]

LGTM, but we should hold of merging until stackabletech/docker-images#1225 is merged.

Can you please also add a docs: prefix to the PR title? :)
If you have the time I would also be happy about a changelog entry that you can now disable the check via configOverrides (yeah, this is a docker-image thing, but users are not going to read docker-images changelog)

[lfrancke]

I thought about that and wasn't sure.
We can also consider whether we want to expose this as a CRD flag.....let's talk about it at the daily and decide how to proceed.

[sbernauer]

Still LGTM, thanks @xeniape for the suggestions!

[NickLarsenNZ]

Left some comments and suggestions.

Hopefully we can remove the SNI workarounds soon.

[NickLarsenNZ]

Not sure who is supposed to resolve or reply to my comments.

[lfrancke]

I hope I caught all comments. It should be ready for review again.

[lfrancke]

I have decided to go with my original proposal for the two comments you disagree with, incorporated another and believe you're wrong about the last.
But if things go the way they usually go I end up being the one that was wrong after all. Let's see :)

[NickLarsenNZ]

Alright, ship it :D

[lfrancke]

Now it has conflicts and I can't merge it from the phone :) I'll try to fix that in the next few days.
