Change default behavior of compact parameter for v2 of the API

[nikki-t]

The current default behavior for application/json responses with an output request parameter set to geojson and without a compact parameter is to return the full GeoJSON response and not compact the data fields into a single GeoJSON Feature.

We should change the default behavior to return a compact response when the compact request parameter is not set when we prepare for version 2 of the API.
