Support Redis username and password in RedisConnector

[Jackson Newhouse]

Right now if you want to connect to a Redis cluster that has a username and password you have to inline it into the connection string, e.g. redis://username:password@host:ip. It'd be nice to be able to specify this on the Redis connection. This'd be added as two optional properties here. I think there should probably a single username/password for the Clustered case as well.

Then, to update the operators, you'll need to use a different IntoConnectionInfo, likely just ConnectionInfo. That would happen here.

Will also need to pick the sql parameters for these options.
