Description

Feature request: Allow authenticating to GCP with service account credentials that use a custom token URI.

We use the service_account credential type. Older versions (oauth2client) supported this type, BUT they only supported using google endpoints for issuing credentials, where we use a custom token_uri to issue credentials. New versions (google-auth) will reference our custom token_uri.
