Helper function that supports XPath style selectors to traverse an object tree e.g.
inst = {'fixed_ip': {'floating_ips': [{'address': '1.2.3.4'}], 'address': '192.168.0.3'}, 'hostname': ''}
private_ips = get_from_path(inst, 'fixed_ip/address')
public_ips = get_from_path(inst, 'fixed_ip/floating_ips/address')
Avoids messy [.get() / if / for]* nested code
