Return ErrorCredentials in lieu of StatusOr<Credentials>
In google/cloud/internal/unified_rest_credentials.cc There are opportunities to refactor some of the helper functions to return an ErrorCredentials containing the Status rather than as part of a StatusOr.
Punt for now, will revisit later.
We think this is done. Scott will write the right comment.
Scott will review.
fixed in #8400
