Code Issues Proposed changes

Add a v2 API endpoint to push DataFrame objects 

A new endpoint has been made available to admin users on
``POST /v2/dataframes``. This will allow end users to push
DataFrames in the form of JSON objects into the CloudKitty
storage.

Documentation and unit tests are included in this commit.
