Igor Duarte Cardoso de694f7164 tox doesn't fail anymore at the py27 environment 
This patch fixes existing specs to totally conform to tox py27 environment
tests as specified by tests/test_titles.py. Semantic information of all
existing specs has not been changed.

Specifically, this patch makes the following changes:
* Fixes all titles and subtitles' capitalization inconsistencies:
  defaulting to only having the first word being capitalized (this seems
  to be the general rule in group-based-policy-specs);
* Adds missing titles and subtitles to some specs;
* Changes tests/test_titles.py for consistency: only 1st word capitalized;
* Changes tests/tests_titles.py: subtitle count inside Testing or
  Documentation impact no longer restricted to 0.

Group Based Policy Driver for Nuage Networks

Launchpad blueprint: https://blueprints.launchpad.net/group-based-policy/+spec/nuage-gbp

Group based policy driver for Nuage Networks

Problem description

Nuage's Virtualized Services Platform(VSP) [1] supports policy based orchestration which fits well with newly defined group based policy framework in openstack. It will enrich the VSP solution by extending its usage through openstack. And also allow openstack user to take advantage of Nuage's fully baked policy driven, application centric service architecture.

Proposed change

We propose the addition of a new GBP driver to support Nuage. It will implement the PolicyDriver interface as defined in the abstract base class services.group_policy_driver_api.PolicyDriver:

We will support CRUD operation on policy-target, policy-target-group, policy-classifier, policy-action and policy-rule resources.

The proposed GBP driver will interface with the Nuage's VSD using ReST channel similar to how its done in Nuage's monolithic plugin. Library will be re-used to avoid code duplication.

Alternatives

None

Data model impact

None (existing GBP model should suffice)

REST API impact

None

Security impact

None

Notifications impact

None

Other end user impact

None

Performance impact

This driver should allow for more efficient and scalable solution for group based policy control of deployments using Nuage's VSP.

Other deployer impact

None

Developer impact

None

Implementation

Nuage's VSD has an inbuilt application centric APIs which will fit nicely with GBP. The driver will act as a proxy for managing coresponding objects on VSD. Nuagenetlib (private python library) will be used to make this call. This is inline with implementation model for nuage's core plugin and ml2 driver. The supported list of resources are mentioned in "Proposed change" section.

Work items

  1. Developing the Nuage GBP driver
  2. Writing corresponding Unit and functional tests

Dependencies

Group Based Policy Plugin

Testing

Unit tests will be provided. Nuage CI may need to be enhanced to support this feature.

Documentation impact

Documentation needs to be updated to reflect the addition of a new GBP driver and its configuration parameters.
