Another createClient overload?

[Janpot]

I would like to propose another overload for the createClient method. One that accepts another client to copy its parameters from.

var client1 = redis.createClient();
var client2 = redis.createClient(client1);

This would help library authors that accept a client as input to clone it to do things like pubsub.

I quite like this idea, but could you not use

var client1 = redis.createClient();
var client2 = redis.createClient(client1.address);

Of course, this wouldn't copy the other options (or database) which could be quite useful.

Sounds reasonable. But I suggest to add a new function instead of overloading createClient further or add a options to the options object. But the later might be more confusing. Using client.clone(options) would also allow to override some old options and copy all others.

This will be released with v.2.4
