Support Redis connection password

Never thought that Redis would have to be secured with authentication, but obviously that's a use case.

The MR implements only one of 2 possible auth mechanisms and it ends up with redis://:password@host:port. I think, this is a colon to much in front of password, isn't it?

When we really implement auth, we should then also implement the ACL method which comes with a username, too. So, password is optional, and if a password is provided, there is also an optional username.

I just added support for username too, good point.

One of the large Drupal-specific PaaS providers does expose Redis to the public internet, so you can debug it easily, then, they of course protect it with authentication.

The problem with the extra colon in front of the password still remains if no username is provided. I've added a code suggestion to the MR for you.

Thx.
