handleSplitRegionBoundaryFailureDuringInitialization will be true for
scanning intermediate chunks in ChunkedResultIterator. When we create scanner
for new chunk we might see stale region boundaries in that case also we need to
forcibly recreate the iterator with new boundaries. In normal case if we get
StaleRegionBoundary exception while creating scanner BaseResultIterator handles
it.
