Add an e2e test that verifies the ObjectStore controller updates the
RBAC Role when an ObjectStore's secret reference changes. The test
creates a Cluster with a MinIO ObjectStore, verifies the Role has the
cluster label and references the original secret, then updates the
ObjectStore to point to a new secret and waits for the Role to be
patched accordingly.
