Support for redis:url configuration

[thom4parisot]

Hello and thanks for your project :-)

I see in the advanced usage there is no way to connect to redis via the url option. Likewise mongo driver, it is very handy to configure everything at once, like redis://user@host:port/db. Cf. redis options

Is there any chance to support this form?

It would make the settings look like this:

var pubsubsettings = {
    type: 'redis',
    redis: require('redis'),
    url: process.env.REDIS_URL,
    return_buffers: true
};
