Title: Output configuration in key sorted order

Hash traversal order is undefined in Ruby. I have seen cases where it
actually will change each Chef run, causing the config to change, and
ultimately causing Riak to restart every Chef run. This forces the
configuration to be outputted in key sorted order every time.
