Steps to reproduce
Create a pipeline with plugin stage having space in them in CDAP 6.2.x
Export the pipeline
Import the pipeline in 6.1.x environment.
Upon import the pipeline studio breaks and fails to import the pipeline.
The failure happens when we try to map the plugin "id" with plugin details in one place and refer to the same via plugin "name" in another place while rendering the pipeline.
The way we parse and generate pipeline JSON is not consistent and typed for us to be able to predict this correctly across multiple places.
