Feature request: cluster mode + non-cluster mode support

[apremalal]

First of all, thanks for the great library. I have a use case of requiring the cache client to be able to use either cluster mode or non-cluster mode. My production environment has a redis cluster but the development has a single node redis. It'd be really helpful if you could expose one interface to handle both cases.
