Currently we can only customize following on Redhat Quay 3.3

BRANDING:
  logo: https://www.example.com/file/gopro.svg
  footer_img: /static/img/RedHat.svg
  footer_url: https://www.example.com
CONTACT_INFO:
- https://www.example.com/help/customer/display.html

However Quay.io has additional footer elements like documentation , security, About, health check , privacy  etc.

Also the health check is currently hardcoded here https://github.com/quay/quay/blob/c688f3a05e47da91ed74ec1faf8b8c63c3be7d5a/static/js/services/status-service.js#L12  so it will end up calling https://8szqd6w4s277.statuspage.io/api/v2/summary.json  we need a way to customize this for Quay enterprise

Additionally all these footer elements are visible on Redhat Quay if we only turn on "FEATURE_BILLING: true" which is not convenient since its on premise installation , this enables billing section in account settings.
