Add CORS support so server can work the vscode test web server.

* When vscode test server runs the frontend will be using a different
  host and port then the backend so we have CORS issues

* Add CORS support to the server so we can use it when developing the frontend

* It looks like the test server or chromium generates a random hostname
  so we need to add special support to CORS to be able to deal with this
