[~xyao] The changes look good to me, but after my commit for KSM, I think it breaks this patch.
Could you please rebase and post this patch again. Thanks in advance

> This is a follow up of HDFS-11504 to add delete block API. For each deleted block, we
will remove the original entry for the block and add a tombstone in the blockstore db. 
> We will add an async thread to process the tombstones and wait for the container report
confirmation to eventually clean up the tombstones.
