Checks if Data Transfer Service valid credentials exist for the given data source and requesting user. Some data sources don't support service account, so we need to talk to them on behalf of the end user. This method just checks whether we have OAuth token for the particular user, which is a pre-requisite before a user can create a transfer config. Args: reference: The project reference. data_source: The data source of the transfer config. transfer_client: The transfer api client. Returns: credentials: It contains an instance of CheckValidCredsResponse if valid credentials exist.

An authorization code is needed if the Data Transfer Service does not have credentials for the requesting user and data source. The Data Transfer Service will convert this authorization code into a refresh token to perform transfer runs on the user's behalf.

Returns: auth_info: A dict which contains authorization info from user.
