Description
During rolling upgrade, datanode create a trash directory for each block pool. Then a block deletion becomes moving the block to trash.
For bumpReplicaGS, it will rename the meta file and then continue writing to the block file. It should copy the original block file and the original meta file to trash in order to support rollback.
