URL: https://github.com/apache/hadoop/pull/5974
### Description of PR
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.
