// GenerateAuthToken is a mighty big test.

//   - Direct connection, non-authenticating proxy, and authenticating proxy.
//   - HTTP or HTTPS backend (to include proxy tunneling).
//   - Non-authenticating and authenticating backend.
//
// In all, there are 44 reasonable permuations (for example, if there are
// problems generating an auth token for an authenticating proxy, we don't
// need to test all permutations of the backend server).
//
// The test proceeds by going over each of the configuration cases, and
// potentially running up to three rounds in each of the tests. The TestConfig
// specifies both the configuration for the test as well as the expectations
// for the results.
