Description
Enhancement
Now mpp don't support warnings.
- cop
- mpp
For supporting warnings, we should acquire warnings from exchange and send warning reponse in MPPTask::finishWrite, just like https://github.com/pingcap/tiflash/blob/e7be8e7f06af59a0359287b9849bdd436666e3b4/dbms/src/Flash/Coprocessor/UnaryDAGResponseWriter.cpp#L61-L72

Research direction
Start at MPPTask::finishWrite and compare its current behavior with dbms/src/Flash/Coprocessor/UnaryDAGResponseWriter.cpp, especially lines 61-72 referenced in the issue. Trace how warnings are acquired from the exchange and verify that MPP sends the corresponding warning response when the write finishes.
