Typical use is to provide functionality like removing persistence of the access token from
the data store. Implementations can assume proper thread synchronization is already taken care
of inside Credential#refreshToken(). Implementations can also assume that Credential#setAccessToken, and Credential#setExpiresInSeconds have already been called
previously with null to clear their values.
