This is a partially fix since it doesn't fully address the dev-side documentation of all GBP related resources. More work needs to be done on top of this to have a full DevRef. Change-Id: I135a3d23a5a1df136c04a7114f94274bd4921cb6 Partial-Bug: #1571385

Group Based Policy Driver for Cisco APIC Controller
Launchpad blueprint: https://blueprints.launchpad.net/neutron/+spec/group-policy-apic-driver
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.
Since the GBP plugin defines a multi-driver based framework to support various implementation technologies (like ML2 for L2 support), a GBP driver is available to support the APIC controller. This driver interfaces with the APIC controller and allows efficient and scalable use of the ACI fabric for policy based control from the GBP plugin.
This driver should allow for more efficient and scalable solution for group based policy control of deployments using an ACI fabric.
Internals
The PolicyDriver interface is defined in the abstract base class gbpservice/neutron/services/grouppolicy/group_policy_driver_api.py: PolicyDriver.
Configuration
The configuration files require specific information to using this driver. These parameters include the addresses, credentials, and any configuration required for accessing or using the APIC controller. Where possible, it shares the configuration with the APIC ML2 driver.
