Add option to automatically re-add and rebalance failed over node when made available again

I'd love it if I wouldn't have to manually re-add the node and rebalance the cluster. Instead of having to babysit an option to automatically rejoin and rebalance after a period of time (say a few minutes) would be amazing. I'm sure the CPU usage issues will be worked out, but not having automatic full recovery is the number one reason why I wouldn't continue to use CouchBase. Galera already does it, and it works beautifully after a EC2 instance failure.
