When writing streamed data into sstables, while using time window
compaction strategy, we have to emit a new sstable for each time window.
Otherwise we can end up with sstables, mixing data from wildly different
windows, ruining the compaction strategy's ability to drop entire
sstables when all data within is expired. This gets worse as these mixed
sstables get compacted together with sstables that used to contain a
single time window.
This series provides a solution to this by segregating the data by its
atom's the time-windows. This is done on the new RPC streaming and the
new row-level, repair, memtable-flush and compaction, ensuring that the
segregation requirement is respected at all times.
Fixes: #2687
