ConfigDrive: convert OpenStack network_data.json to network_config.yaml

OpenStack clouds may provide network_data.json information via the
MetadataService in ConfigDrive.

Teach ConfigDrive to read, store and convert the data into network_config
yaml format. Making this available allows cloud-init to read network
config from OpenStack and use the distro.apply_network_config() method to
render the network_config from OpenStack into a distro network
configuration file.
