BigQuery authentication on remote servers
Hello, I can't get the BigQuery auth to work on remote servers:

```
WARNING:root:This function, oauth2client.tools.run(), and the use of the gflags library are deprecated and will be removed in a future version of the library.
Your browser has been opened to visit:

    big-url-here

If your browser is on a different machine then exit and re-run
this application with the command-line parameter

  --noauth_local_webserver
```

Even if I try to open that URL on my workstation, it tries to redirect me to a local server. The documentation says that:

> Should the browser not be available, or fail to launch, a code will be provided to complete the process manually.

however, I've yet to see this alternative.

Any help?
