test(smoke): Apply secrets before the OpenSearch cluster to avoid restarts

Description

Apply secrets before the OpenSearch cluster to avoid restarts

The smoke test deployed the Secret opensearch-security-config together with the cluster. After the restart controller was enabled (#97), restarts occurred if this Secret was processed after the StatefulSet. If a restart happened then metadata.generation was 2 instead of the expected 1 at the StatefulSets and the smoke test failed.
