// In this way, if the other cleanup failed, this will retry it. If it had

// This function first calls the CommitChanges() method of the PostConfigManager
// (which will inform resource types and memberset listeners that this node
// has been evicted). It then cleans up the base cluster.

// Arguments:

// Pointer to the IPostCfgManager interface
//
// IEnumClusCfgManagedResources * peccmrIn
// Argument needed by the IPostCfgManager::CommitChanges()
//
// IClusCfgClusterInfo * piccciIn

//
// IClusCfgBaseCluster * piccbcaIn
// Pointer to the IClusCfgBaseCluster interface that is used to clean up
// the base cluster.
