🔧(ngnix) adapt nginx development

We adapt the nginx configuration to works
with http requests and on the collaboration routes.
Requests are light but quite network intensive,
so we add a cache system above "collaboration-auth".
It means the backend will be called only once
every 30 seconds after a 200 response.
