Statically Render only the "Content" section of Site pages

[acouch]

Would like to have a configuration option to statically render the site with data that is included from the API set in the REACT_APP_INTERRA_API_URL.

This ticket is to have an option to statically render only the "content" sections of HTML pages.

For the "search" page ONLY the first level route should be included. We don't want to render every single search possibility.
