The issue includes 2 parts :

1. Change the error logs level for RemoveBlocks RPC
2. Add some error logs for RemoveShuffleMerge RPC.

1 is completed for RemoveBlocks but RemoveShuffleMerge doesnt use RPC send so can't infer onSuccess and onFailure in it.

Should this client.send be replaced with client.sendRpc for RemoveShuffleMerge and implement similar to RemoveBlocks?
