server/auth: Add TokenSource call.

Add a call to return an oauth2 AsSelf TokenSource from the server/auth
package.

This allows the "server/auth" package to be used with Google API
clients. Specifying manual per-RPC credentials hits a problem with the
automagic setup detailed here:
https://github.com/google/google-api-go-client/issues/186

Consqeuently, gRPC service libraries (Cloud Datastore, BigTable, Pub/Sub,
etc.) require a TokenSource to be provided explicitly.

Also make all auth tests run in parallel :)
