MB-7506: Allow percentages to change high and low watermarks (Revision 0b100d2e6be9f00cf2715db9af8d97472966aed4)
Result = SUCCESS
We already keep the number of bytes in this stat so it isn't necessary to also have the percentages. The commit commented on above also accidentally had the wrong commit id in it.
