 While researching CASSANDRA-8457 we found that it is effective and can be 
 done without introducing additional latency at low concurrency/throughput.
 The patch from that was used and found to be useful in a real life scenario 
 so I propose we implement this in 2.1 in addition to 3.0.
 The change set is a single file and is small enough to be reviewable.

Running some experiments I can see a big improvement with this ticket on a 6 
node RF=3 cluster writing at QUORUM.

The left half is without the patch the right half is with. From steady state of 
80k/sec to a steady state of 120k/sec

I will mention I get similar results by using nagle. However just enabling 
nagle will cause small requests to slow down where as this approach adjusts.
