Mimetype: application/vnd.dataresource+json

I'm not sure if this belongs here or across every single kernel we'd want to target. For Spark DataFrames in particular, I'd like to see a standardized table come back. The leg work was done in Pandas, nteract, and a Jupyter notebook/lab extension to prove this out.
