Java environments (e.g. Java 6, Android 2.3, App Engine, or All)?

App Engine only.

Please describe the feature requested.

Unfortunately AppIdentityCredential 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.  So no code needs to be changed 
between running locally and in production, this is wrapped by something like:

HttpRequestInitializer httpRequestInitializer;
if (com.google.appengine.api.utils.SystemProperty.environment.value() == 
com.google.appengine.api.utils.SystemProperty.Environment.Value.Development) {
  httpRequestInitializer = new ServiceAccountCredential....;
} else {
  httpRequestInitializer = new AppIdentityCredential....;
}

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