Add support for following links to lists

Currently the "follow_link" method of the "Conection" class only
supports links to single objects, but not links to list of objects. This
patch changes the SDK so that it will also support this kind of links.
For example, when a VM is retrieved it will include links to its NICs:

<vm id="123" href="/vms/123">
  <link rel="nics" href="/vms/123/nics"/>
  ...
</vm>

The SDK will process this "link" element and store it in the "vm.nics"
property of the created object. Later, the user will be able to use the
"follow_link" method to retrieve that list:

vm = ...
nics = connection.follow_link(vm.nics)
for nic in nics:
    print("nic: %s" % nic.name)
