/**
 * Creates a gRPC interceptor that authenticates each RPC before it starts.
 *
 * Each attempt uses a copy of the caller metadata, so a retry does not add a
 * second authorization header. The interceptor passes the remaining RPC
 * deadline to the authenticator as a timeout budget. A custom authenticator
 * that ignores this budget is not forcibly stopped. When authentication cannot
 * retry, the interceptor completes the RPC with `UNAUTHENTICATED` and does not
 * contact the service.
 *
 * SDK users do not normally call this function. Use it when assembling a
 * custom gRPC client with a {@link Provider}.
