fix(kuma-cp): enable hash-suffix only if Zone has KDS feature

[lobkovilya]

Depends on #8450

It was a mistake to introduce a feature flag for hash-suffixes. We have KDS features, so we can easily check if Zone has a fix to handle MeshGateway renaming.

Checklist prior to review

• 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 -- It will break, I'll handle it in upgrade PR.
• 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) --
