Mikołaj Sielużycki a88f7df195 memtable-sstable: Add compacting reader when flushing memtable. 
When memtable contains both mutations and tombstones that delete them,
the output flushed to sstables contains both mutations. Inserting a
compacting reader results in writing smaller sstables and saves
compaction work later.

Performance tests of this change have shown a regression in a common
case where there are no deletes. A heuristic is employed to skip
compaction unless there are tombstones in the memtable to minimise
the impact of that issue.
