------------------------------------------------

Good to see client connection sharing. It is a required feature.
For the multiPut support, recently we added 'bufferSize' and that will help to
control when to flush from client side. MultiPut is more on the number of puts
to be grouped than the size. Seems both could be useful.
> Add multiPut support and other miscellaneous to PE

> Add some useful stuff and some refinement to PE tool
> 1. Add multiPut support
> Though we have BufferedMutator, sometimes we need to benchmark batch put in a
> certain number.
> Set --multiPut=number to enable batchput(meanwhile, --autoflush need be set
> to false)
> 2. Add Connection Number support
> Before, there is only on parameter to control the connection used by threads.
> oneCon=true means all threads use one connection, false means each thread has
> it own connection.
> When thread number is high and oneCon=false, we noticed high context switch
> frequency in the machine which PE run on, disturbing the benchmark
> results(each connection has its own netty worker threads, 2*CPU IIRC).
> So, added a new parameter connCount to PE. set --connCount=2 means all
> threads will share 2 connections.
> 3. Add avg RT and avg TPS/QPS statstic for all threads
> Useful when we want to meansure the total throughtput of the cluster
> 4. Delete some redundant code
> Now RandomWriteTest is inherited from SequentialWrite.
