Both streaming and repair call the distributed sstables writing with
equal lambdas each being ~30 lines of code. The only difference between
them is repair might request offstrategy compaction for new sstable.
Generalization of these two pieces save lines of codes and speeds the
release/repair/row_level.o compilation by half a minute (out of twelve).
