Mariell Hoversholm f7b9f1ce69 Unified Storage: Return an already exists error (#102857) ...

* Unified Storage: Return an already exists error

When inserting a resource that already exists (i.e. race condition), we can safely catch UNIQUE constraint violations
and transform them into a `k8s.io/apimachinery/pkg/api/errors` error that stands the test of `errors.IsAlreadyExists`.
