Do we set each operator individually or set the parallelism uniformly? @ashulin

@liugddx My opinion is the same as the [spark scenario] #2965, the user can set the parallelism of a single source and sink, and can also set the global parallelism. When the parallelism of the plugin does not exist, the global parallelism is used.

I found that some operators are specified in parallelism itself.like jdbcSource and jdbcSink.Should we have uniform Settings? like this pr.

@liugddx I would like to have uniform the parallelism option Settings
