Suppose we have following scenario. I created cluster with direct engine, after that I switched to Heat engine and removed cluster. After that, cluster will be removed from Sahara DB, but instances will be alive. This patch propose to add following: if we try to delete direct-engine-created cluster with heat engine, we will try to delete cluster in same way, like direct engine do it.
