Partially implements blueprint nova-api-samples
fixes bug 1130609
The XML serializer for the update method in the os-services API extensions was
not serializing the "updated_at" field because of a typo in the code.
In this change we added api_samples for the XML output.

Updates the os-services API extension so that it is consistent
internally (index and update return similar formats), and so
that it works with the recent novaclient code which sends
the following request body format:
{"binary": "nova-cert", "host": "nova1"}
Also, updates the response body format of the update call so that it
wraps things in an extra service dict which should make novaclient
happier here as well (and is consistent with other extensions too).
Fixes LP Bug #1147746.
