Restore arrays as arrays after json-decoding Zookeeper configs #20
Description
Config data is stored in Zookeeper with its arrays converted to hashes, so ["a", "b"] becomes { 0 => "a", 1 => "b" }.
To make sure the config data gets restored in its original format after getting it back from Zookeeper, I've added numhash_to_array_r() in mschilli/pogo@1f59cee.
