Kue has a different options configuration than redis.createClient

[alex-h-strachan]

Use case - I would like to use a redis configuration with both a URL and options, like

const kueOptions = {
    redis: { url: 'my-connection-url', tls: { servername: 'my-servername' } }
}

I've provided a PR and a more detailed description https://github.com/Automattic/kue/pull/1178
