we have the following validation rules introduced:

focus only on cluster type

PR https://github.com/percona/percona-server-mysql-operator/pull/308 was updated with all the rules we need and indeed with Kubernetes v1.29 validation works well.

The issue we faced is that env tests don’t pass with certain rules, there is an unclear issue as to why certain rules are not evaluated properly while running in envtest environment, but on a cluster like GKE work properly.

More time is needed to find what is causing this and how to fix it. We need to have all of these rules passing in our integration tests.

We have added CRD validation rules to properly tackle this issue and the PR is ready (although might be updated when we revisit it) - https://github.com/percona/percona-server-mysql-operator/pull/308

The issue with validation rules is that they are only supported from k8s 1.25 and we simply can't restrict PS operator for only this version, we need to have it running on couple of older versions.
