Doc Text:	Setting only one of the thresholds for power saving/evenly distributed memory based balancing (high or low) can lead to unexpected results. For example, when in power saving load balancing the threshold for memory over utilized hosts was set with a value, and the threshold for memory under utilized hosts was undefined thus getting a default value of 0. All hosts were considered as under utilized hosts and were chosen as sources for migration, but no host was chosen as a destination for migration. This has now been changed so that when the threshold for memory under utilized host is undefined, it gets a default value of Long.MAX. Now, when the threshold for memory over utilized hosts is set with a value, and the threshold for memory under utilized host is undefined, only over utilized hosts will be selected as sources for migration, and destination hosts will be hosts that are not over utilized.
