    I think this change will result in a RPC per thread using the batch writer.    If 3 threads
add mutations for the same tablet server, then it will no longer send all of those in one
RPC.   If 100 threads add mutations for 100 tablets server, the batch writer will make ~10,000
RPCs instead of ~100.
    
    I have some idea on how to improve the batch writer based on what I learned while writing
the conditional writer, I will try to write those up.  It may or may not be useful.
