Description

WatermarkSpec#toString only include rowtimeAttribute and watermarkExpressionString.

Maybe we should inlcude watermarkExprOutputType too, just like:

@Override
public String toString() {
   return "rowtime: '" + rowtimeAttribute + '\'' +
      ", watermark: '" + watermarkExpressionString + '\'' +
      ", outputType: '" + watermarkExprOutputType + '\'';
}
