Setup dialog for remoting

Adding more setup content to remoting. Including the gaia authenication
and done message. This provides the basic flow for the setup.

There's a lot still needs to be worked on:
1. Merge RemotingSetupFlow and RemotingSetupMessageHandler because we shouldn't
   splitting the logic into two separate classes.
2. Cleanup the memory ownership.
3. Perform the actual gaia login.
4. Perform host registration.
