Streamline data returned by the API

[pombredanne]

There is too much data returned by default in API listings.

• too many records: 100 is too much at once
• too much data: we return the whole details in the details

We should review and design a better API to get less details.

Just to provide a user perspective: we have a need to present a list of Packages, and the main thing we want to know when presenting the list is Yes/No is there a vulnerability for that Package, and note that we use a PURL to identify each package. After that, the user can drill down on a specific package to get the details (Summary, Reference IDs, Reference URLs) and we certainly would like to be able to get the "fixed packages" information when that is ready.
