> 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.
