Description

Currently, hbck sidelines some regions to break big overlap groups to avoid possible compaction and region split. These sidelined regions should be
bulk loaded back later. Information about these regions is in the output.

It will be much easier to group them together under the same sideline rootdir,
for example, /hbase/.hbck/to_be_loaded/. If so, even we lose the output
file, we still know what regions to load back.
