The existing GoogleDrive implementation always needs a service account to be available at the credentials location. When running on GCP services such as Cloud Run, a service account already exists in the metadata of the service, so no physical key is necessary. This change adds a check to see if it is running in such an environment, and uses that authentication instead.
