Description

In this method, we will copy all the fields, including RegionName and EncodedRegionName of the RegionInfo, so after we changed some other fields like start key or stop key or replica id, and then create a new RegionInfo, the RegionName of the RegionInfo will not be regenerated and cause problem.
