Considering this configuration:

```yaml
framework:
    messenger:
        transports:
            queue:
                dsn: '%env(MESSENGER_TRANSPORT_DSN)%'
                options:
                    stream: 'cms'
                    delete_after_ack: false
                    auth: 'pa$$word'
                    serializer: !php/const Redis::SERIALIZER_JSON
```

It results to this error:

```
In Connection.php line 510:

  NOAUTH Authentication required.
```

Because the `auth` option was never read from the options, only from the parsed DSN.

This fix allows users to use `auth` option from the configuration.

I target 5.3, as 5.2 is going to be unmaintained at the end of July
