Chris Smith d0670ef3b1 google: Wrap token sources in errWrappingTokenSource
Introduce new AuthenticationError type returned by
errWrappingTokenSource.Token. The new error wrapper
exposes a boolean method Temporary, identifying the
underlying network error as retryable based on the
following status codes: 500, 503, 408, or 429.

Bump go.mod version to 1.15
