docs: remove annotations-based l7 visibility

[networkop]

L7-based annotations have had little adoption and are causing a lot of bugs. This change is to move them to the background in the docs and bring forward the more standard way of enabling L7 visibility (CNP)

Looks great! I just have a couple of suggestions. Also, can you add a note about this in the upgrade guide: https://github.com/cilium/cilium/blob/main/Documentation/operations/upgrade.rst#115-upgrade-notes?

👍, my review can be counted from proxy team. I had a chat with Michael offline before as well.

@networkop Given its docs we don't need to run the whole test suite, is this "ready-to-merge"?

[networkop]

@dylandreimerink yes, it's ready to merge from my pov.

[joestringer]

@dylandreimerink CI should detect that it's only docs and skip the other tests. This way we can just run CI on every PR, and not debate about ready-to-merge from CI perspective. If this is triggering full CI then we can iterate on the detection, I would consider that a CI bug. I'm trying to get us to a point where we don't try to make judgement calls about whether to skip CI or not, because that often becomes a point of failure in the process where we let buggy logic into the tree.
