> in 0.99, HRegionServer is the base class of HMaster. 
> master and regionserver share the same run method, the master instantiates both MasterCoprocessorHost and RegionServerCoprocessorHost
> below is example logs, a coprocessor is start/stop twice--one is for real regionserver, the other is for the RegionServerCoprocessorHost in master.
