Subject: [PATCH 1/6] Initial version of websockets notification support.

For now only folder notifications are sent (create, rename, delete).
The notifications are only tested between two web-vault sessions in different browsers, mobile apps and browser extensions are untested.

The websocket server is exposed in port 3012, while the rocket server is exposed in another port (8000 by default). To make notifications work, both should be accessible in the same port, which requires a reverse proxy.

My testing is done with Caddy server, and the following config:

```
localhost {

    # The negotiation endpoint is also proxied to Rocket
    proxy /notifications/hub/negotiate 0.0.0.0:8000 {
        transparent
    }

    # Notifications redirected to the websockets server
    proxy /notifications/hub 0.0.0.0:3012 {
        websocket
    }

    # Proxy the Root directory to Rocket
    proxy / 0.0.0.0:8000 {
        transparent
    }
}
```

This exposes the service in port 2015.

 Note that you need to mount ssl files and you need to forward appropriate port.
 
+### Enabling WebSocket notifications
+*Important: This does not apply to the mobile clients, which use push notifications.*
+
+To enable WebSockets notifications, an external reverse proxy is necessary, and it must be configured to do the following:
+- Route the `/notifications/hub` endpoint to the WebSocket server, by default at port `3012`, making sure to pass the `Connection` and `Upgrade` headers.
+- Route everything else, including `/notifications/hub/negotiate`, to the standard Rocket server, by default at port `80`.
+- If using Docker, you may need to map both ports with the `-p` flag
+
+An example configuration is included next for a [Caddy](https://caddyserver.com/) proxy server, and assumes the proxy is running in the same computer as `bitwarden_rs`:
+
+```r
+localhost:2015 {
+    # The negotiation endpoint is also proxied to Rocket
+    proxy /notifications/hub/negotiate 0.0.0.0:80 {
+        transparent
+    }
+    
+    # Notifications redirected to the websockets server
+    proxy /notifications/hub 0.0.0.0:3012 {
+        websocket
+    }
+    
+    # Proxy the Root directory to Rocket
+    proxy / 0.0.0.0:80 {
+        transparent
+    }
+}
+```
+
+Note: The reason for this workaround is the lack of support for WebSockets from Rocket (though [it's a planned feature](https://github.com/SergioBenitez/Rocket/issues/90)), which forces us to launch a secondary server on a separate port.
+
 ### Enabling U2F authentication
 To enable U2F authentication, you must be serving bitwarden_rs from an HTTPS domain with a valid certificate (Either using the included
 HTTPS options or with a reverse proxy). We recommend using a free certificate from Let's Encrypt.
