Review Comment:
After some more thoughts, I moved from using `snapshot-range` to these
properties. I think the range approach cannot describe a few situations like
(1) inclusive start and inclusive end, (2) no end snapshot. These are all
supported features in the Java IncrementalSnapshotScan API, so I think it is
better to go with this start and end snapshot approach to cover all those
cases. Let me know what you think @rdblue !
