-------------------------------
Description: The {{setParallelism()}} method exist in many components from
different levels. Some of the methods require the input value to be greater
than {{1}} (e.g., {{StreamTransformation.setParallelism()}}), while some of
them also allow the value to be {{ExecutionConfig.PARALLELISM_DEFAULT}}, which
is {{-1}} by default (e.g., {{DataSink.setParallelism()}}). We need to unify
the value checks for these methods. (was: The {{setParallelism()}} method
