Feature/updated oonib policy aware

hi,
I have decided to get the policy aware changes and create a new branch to a avoid a lot of outdated code and merge conflicts.
I have a couple improvements that i haven't coded yet:
1) The policy API uses policy.yaml, i think it should now use the bouncer.yaml to publish the policy information of the bouncer through the policy API to avoid information duplicated and the following annoyances that it provokes.
2) I think that the bouncer API should be splitted in two different subpaths, one for the test-helpers and the other for the net-test. This way the API is more RESTful and depends less on the payload of the POST requests to select between the two methods that the bouncer API supports.
ciao
