Video in section container

This adds a "More videos in section" container to the bottom of the video content page as per our design. It uses the multimedia container and creates a new endpoint to query the CAPI. 

Apologies for the usual weird diff'ing in the routes files.

@kaelig this is just a white space change, no refactoring.
