Ability to run multiple operators in the same cluster to rollout new versions with confidence.

As stated here by Alen:

Infrastructure operators often want ability to run multiple Checkly operator versions in parallel prior to doing full switch, to build confidence. Here the only requirement would be to to define which CR(D)s are used for which deployment, as Istio does for example. Meaning, in practical terms, you need resource annotation with unique identifier and Checkly operator deployment configured to consume only those matching resources. You do not want multiple operators consuming the same resources — that's big no-no.
