As a user, I want to receive a JSON response that contains the PDS4 label metadata in JSON format (application/vnd.nasa.pds.pds4+json)

[jordanpadams]

💪 Motivation

...so that I can search for and parse the metadata for a particular product in a JSON-structured form. This will keep the nesting that comes with XML, enabling robust client applications to use that metadata.

📖 Additional Details

⚖️ Acceptance Criteria

Given an ingested PDS4 product
When I perform an API query for that product using the endnpoint /products/{lidvid}
Then I expect the response to look something like this:

⚙️ Engineering Details

• update harvest to ingest JSON blob
• add new response format to API spec
• update API service to output JSON from blob

[tloubrieu-jpl]

We will rename the MVC marshaller for application/json from Pds4JsonProductSerializer to JsonProductSerializer.

@eugene will create a new MVC marshaller Pds4JsonProductSerializer

@jordanpadams - can you confirm we want this behavior extended to the list of products endpoint as well?
