Add connection type to web sockets

This allows the backend to distinguish them.  In our case we use them to count a
single "open" of Code so we need to be able to distinguish between web sockets
from two instances and two web sockets used in a single instance.

To test this,
1. Run code-server
2. Open Network tab in Browser DevTools and filter for websocket requests
3. You should see the `type=<connection-type>` in the request url
