CONTAP-800619: Allow configuration of max RAL burden
Issue
A FlexCache origin volume shows a significant amount of space used for RAL metadata reservations, or the logical-used size of a SnapMirror source volume that is also a FlexCache origin volume is significantly larger than the logical-used size reported on the SnapMirror destination volume, or the performance of a FlexCache cache volume is found to be limited by the space consumed for metadata reservations at the origin.
