Update Topgear site so it’s mostly controlled by Contentful similar to zurich and cs

[Oanh-and-only-Oanh]

Currently, other than the banner and the FAQ page Topgear's portal is all hard coded into the app. We want to make it so it's controlled by Contentful.

@kkartunov, Topgear site on dev env works as on prod except for the below differences.
Home page:

1. Initiate Project URL includes user_id param in prod while it is missing here.
   PROD: https://topgear-app.wipro.com/topcoder_projects/initiate_project?user_id=xxxxxx
   FEATURE BRANCH: https://topgear-app.wipro.com/topcoder_projects/initiate_project

2. Differences in style in the home page and footer
