Deprecated: Checks the existence of a refresh token for the EUC user for a given connection and returns its details. Use dataConnector.acquireAccessToken instead and then check the validity of the returned token by asking the 3rd party system. There's no way to know for sure if a refresh token is valid without asking the 3rd party system.
