    [fix][python]Fix generated Python protobuf code not compatible with latest 
protobuf package (#15846)
    
    * [fix][python]Fix generated Python protobuf code not compatible with 
latest protobuf package
    Protobuf latest 4.21 (v21) version broke compatibility with files generated 
with protoc < 3.19
    This fix downgrades protobuf python package to 3.20.1.
    See https://developers.google.com/protocol-buffers/docs/news/2022-05-06
    
    * Limit protobuf version to 3.20.* in setup.py
