Persistence mechanism for QoS 1 and 2 incoming and outgoing messages

To properly support QoS 1 and 2 the messages should be persisted during the handshakes. It's common to offer a memory persistence instance that is ephermeral but suffices while the server is running, and another more persistence instance. For the latter I'm thinking of using Redis.

I suggest you to try LevelDB. I used it for http://npm.im/mosca and it's awesome!

I haven't tried leveldb before, I'll give it a look thanks.
