`IdentityToken()` contains opaque registry authentication data suitable for
`PullImageOptions::RegistryAuth()` or `PushImageOptions::RegistryAuth()`. `TokenType()` identifies
whether it represents an identity token or the supplied credentials.

auto authentication = session.Authenticate(registryUri, username, password);
pullOptions.RegistryAuth(authentication.IdentityToken());
