Client plugin changes to support third party authentication.
This creates a TokenFetcher implementation that on the client that uses the webapp to direct the user to fetch a token and secret from the given token URL. If the URL requires interactive authentication, the webapp will open a tab/window for the user to authenticate. Once the webapp has a token and shared secret, it uses the callback to send it back to the authentication layer.
This also glues the third party authentication method to the NegotiatingAuthenticator.
