Description

Now the rbf trash with multi cluster mounted  in HDFS-14117 , the solution is not graceful。
If we can move the client side trash (mkdir and rename) to the  server side, we can not only solve the problem gracefully, but also reduce the trash rpc load in server side to about %50 compare to the origin trash which call two times rpc(mkdir and rename).
