   ## Purpose of the pull request
   
   the performance of one master server is stable, and we should make sure the
   master server have stable throughtouput, as we all know, there will be 
server 
   master in the cluster, 
   
   the fetchNum in the config is static, and when other master server shutdown,
   foro code we will know, the active server will process more command which is 
unstable
   and will make side effect, 
   
   and actually now master server size do not take effect when fetch commnad 
which 
   do not take the idea of performance improvement in ds 2.0,
   
   we the command should depend on the master server size which get from zk, 
and user 
   config fetchNum
   
   ## Brief change log
   
   change the 
   
   ` int pageSize = masterConfig.getFetchCommandNum() * 
ServerNodeManager.MASTER_SIZE;`
