Add support for Redis instances with a password

[iBobik]

The problem faced currently?

Currently it can connect only to Redis without authentication, because username and password is not passed to a client, just hostname and port.

How can we solve it?

Parse all parts of a connection string URL.

Ideally support Heroku's format of Redis add-on which looks like this:

REDIS_URL=redis://:[email protected]:7919
REDIS_TLS_URL=rediss://:[email protected]:7920

If you want this feature to be implemented, give it a thumbs up reaction, so that we can determine which features are important to you.
