+STAGE DEPENDENCIES:
Review comment:
1. Moved `STAGE DEPENDENCIES` and `STAGE PLANS` constants to
`DagJsonParser` so these can be accessed from both `DagJsonParser` and
`ExplainTask`
2. In formatted mode If dependencies and plans are empty json objects do not
add them to the final json.
3. In normal mode added check if task is empty do not print these to output
