ConfigureDatastoreIORM_Task

Changes configuration of storage I/O resource management for a given datastore. The changes are applied to all the backing storage devices for the datastore. Currently we only support storage I/O resource management on VMFS volumes. In order to enable storage I/O resource management on a datstore, we require that all the hosts that are attached to the datastore support this feature.

This method is only supported by vCenter server.
