As a python user, when running deephaven_server.Server on my own machine, I expect the browser to launch automatically after the server is ready. Failing that (or: "In addition"), I expect to see as accurate of a URL as is possible logged, which may include the auth mechanism.
It looks like jupyter notebook uses the webbrowser module to achieve this, but we still need to offer an API call for AuthenticationRequestHandlers to customize the URL, so that when PSK is the default handler the user can automatically have the browser launched for them.
We should consider a matching issue for launching the jetty main directly.
