Add read only HTTP filter to prevent PUT/POST/DELETE

The filter intercepts all HTTP requests and rejects any PUT, POST
or DELETE with a "503 Service Unavailable" status code [1].

This prevents:

- Creating a new project from the UI
- Changing a project's configuration from the UI
- Changing user preferences from the UI
- and any other operation performed by a POST/PUT/DELETE REST API call
