Pecan: quota management API broken

[Salvatore Orlando]

The quota management APIs in Pecan simply do not work.

The pecan controller framework try to treat quota as a resource, and even create resource and collection controllers for this resource. However, this fails as the plugins do not implement a quota interface.

In the current WSGI framework indeed quota management is performed by a special controller which interacts directly with the driver and implements its own authZ logic.

The pecan framework should implement quota management correctly, possibly avoiding to carry on "special" behaviours from the current WSGI framework

    Pecan: fix quota management

    This patch fixes quota management APIs in the Pecan framework.
    To this aim:

    1) an ad-hoc pair of collection/item controllers are introduced
       for the quota resource; as the new controllers have been added
       in a separate module, the neutron.pecan_wsgi.controllers.utils
       module has been added as well for helpers, routines and classes
       used by all pecan controllers;
    2) the quota API extension is made pecan-aware, meaning that it
       simply returns a Pecan controller instance rather than deferring
       the task to the startup process that builds controllers using the
       home-grown WSGI framework ext manager;
    3) the quota resource is now "almost" a standard neutron resource;
       unfortunately since it does not yet have its own service plugin a
       special provision is made in the attribute population hook in
       order to ensure the object is loaded for allowing correct
       policy enforcement.
    4) Functional tests for the quota controller have been added.
