runzhiwang updated HDDS-4376:
-----------------------------
Description:
When scm receives TruncateScmKeyRequestProto, for the deleteBlocks, scm has
already implemented the code.
For the partialTruncateBlocks, we process it as a transaction like
deleteBlocks, store <transactionId, TruncatedBlocksTransaction> in
truncatedBlocksTable, and return succ to OM.
We abstract the code related to delete block transaction, so that truncate and
delete blocks can share the abstract code.
> SCM create transaction for truncated blocks
