Compute Engine only.

Please describe the feature requested.

Unfortunately ComputeCredential only works in production.  So typically in 
order to test the app locally, a developer needs to use service accounts using 
ServiceAccountCredential when running locally.  Ideally one would find some 
mechanism to determine if the code is running in production, so that no code 
needs to be changed between running locally and in production, to end up with 
something like:

HttpRequestInitializer httpRequestInitializer;
if (running locally) {
  httpRequestInitializer = new ServiceAccountCredential....;
} else {
  httpRequestInitializer = new ComputeCredential....;
}

We can simplify this developer experience by combining the functionality of 
ServiceAccountCredential into ComputeCredential, so the developer can specify 
the service account to use when running locally.
