feat(kuma-cp): implement delta xDS for envoy config exchange

[lukidzi]

Checklist prior to review

• Introduce experimental feature delta xDS for envoy configuration exchange
• Allow to configure single DP, and whole deployment to use delta xDS
• We can run a separate job with E2E just for delta

Requires: envoyproxy/go-control-plane#981
and upgrade of go-control-plane with a fix for #9580

• Link to relevant issue as well as docs and UI issues --
• This will not break child repos: it doesn't hardcode values (.e.g "kumahq" as a image registry) and it will work on Windows, system specific functions like syscall.Mkfifo have equivalent implementation on the other OS --
• Tests (Unit test, E2E tests, manual test on universal and k8s) --
  • Don't forget ci/ labels to run additional/fewer tests
• Do you need to update UPGRADE.md? --
• Does it need to be backported according to the backporting policy? (this GH action will add "backport" label based on these file globs, if you want to prevent it from adding the "backport" label use no-backport-autolabel label) --

Do we still need this switch ?
Or just enable the rest, sotw, delta simultaneously?
