Config-drive is an alternate no-network method for publishing local instance metadata on OpenStack. This change implements support for fetching data from config-drive, and tries it before querying the network metadata service (since config-drive will fail quickly if not available). Note config-drive involves mounting the filesystem with label "config-2", so anyone using config-drive and running kubelet in a container will need to ensure /dev/disk/by-label/config-2 is available inside the container (read-only).
