Add a JSON export to the download tab

[briri]

Allow users to download their plan as JSON - use the new api/v1/plans/:id JSONP functionality

Works for me, though I haven't checked the json in detail for completeness or anything.

Confirming that I am able to download plans as json. It does not currently include narrative components of the plan.

Can I just check - what are exactly the fields from the DMP that we were hoping to appear in the JSON download?

We are following the new metadata standard for DMPs outlined by the RDA working group for maDMP functionality.

As we begin to use the new standard for the FAIR Island project, we are starting to identify gaps between the standard and what we need for DMPRoadmap to function properly.

For example, there is a place to add narrative elements for things like the preservation, security and privacy statements but at an individual dataset level. We do not yet have the ability to accommodate that level of granularity though until we begin capturing multiple dataset info.

We have a ticket open to port over the functionality currently available in the v0 of the API #2567 but in order to do so we are also working on RDA-Common-Standard issue #27 to determine the best way to fill those gaps

We will likely have a hybrid solution over the next month or two where we stuff the narrative into a dmproadmap-narrative extension to the common standard.
