Create response filter that adds cache-control headers

In a few instances, we've encountered an issue with NGINX caching some results for a few minutes. In most cases this is desired and expected. However, when it is not desired, we need to be able to disable it. We currently have an easy solution that leverages undertow, as seen here: eclipse-openvsx-api#18 (closed)

For our use case, Undertow reads the undertow-handlers.conf file and adds the following cache breaking headers to all outbound GET responses:

• cache-control: no-cache, no-store, must-revalidate
• pragma: no-cache
• expires: 0

We should think about how we want to configure a filter that adds these same headers on GET requests. We could have it enabled=false by default. All we would need to do is enable it on a project by project basis
