// Interface of a OAuth2 access token fetcher.
// Usage:
// * Create an instance with a consumer.
// * Call Start()
// * The consumer passed in the constructor will be called on the same
// thread Start was called with the results.
// This class can handle one request at a time. To parallelize requests,
// create multiple instances.
