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 Cisco APIC Controller

Launchpad blueprint: https://blueprints.launchpad.net/neutron/+spec/group-policy-apic-driver

GBP plugin has defined a multi-driver based framework to support various implementation technologies (like ML2 has done for L2 support). This blueprint proposes a Group Based Policy (GBP) driver to enable GBP plugin to be used with Cisco APIC controller.

Problem description

Cisco APIC controller enables you to create an application centric fabric. If you require a policy driven network control in an openstack deployment using the ACI fabric, the reference driver for GBP can not leverage the efficiency or scalability provided by the native fabric interfaces available in the APIC controller.

Proposed change

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

The proposed GBP driver will interface with the APIC controller and allow efficient and scalable use of the ACI fabric for policy based control from GBP plugin.

Alternatives

There are no alternatives to use the native capability of the ACI fabric for policy based control from openstack APIs.

Data model impact

None (existing models for GBP should suffice to capture policy for ACI)

REST API impact

None

Security impact

None

Notifications impact

None

Other end user impact

The configuration files will need to be updated for using this driver. These parameters include the addresses, credentials, and any configuration required for accessing or using the APIC controller. Where possible, it will share the configuration with APIC ML2 driver.

Performance impact

This driver should allow for more efficient and scalable solution for group based policy control of deployments using an ACI fabric.

Other deployer impact

As above, there is a configuration impact.

Developer impact

None

Implementation

Work items

  1. Developing the APIC GBP driver

Dependencies

Group Based Policy Plugin

Testing

Unit tests will be provided.

Since access to an APIC controller is required for testing the proposed changes, 3rd party testing is required and will be provided by Cisco CI system.

Documentation impact

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