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 OpenDaylight Controller
Launchpad blueprint: https://blueprints.launchpad.net/group-based-policy/+spec/gbp-odl-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 OpenDaylight (ODL) controller.
Problem description
The Group Based Policy blueprint has proposed new application centric APIs for Neutron. Similar to the work in Neutron, there is work in the OpenDaylight project to implement these APIs as well. With the APIs being implenented in both of these open source projects, we propose a GBP driver to allow OpenStack GBP to orchrestrate ODL GBP
Proposed change
The proposed change will: 1. Add a new ODL GBP Policy Mapping Driver to support OpenDaylight GBP. It will implement the PolicyDriver interface as defined in the abstract base class services.group_policy_driver_api.PolicyDriver, as documented in the GBP BP. The proposed GBP/ODL Mapping Driver will interface with ODL controller for GBP related operations, and with Neutron ML2 for network/subnet/port related operations.
- Add a new ODL GBP Mechanism Driver for Neutron ML2 Plugin. Such a mechanism driver will provide a feedback loop to the ODL GBP Policy Mapping Driver to trigger policy target related operations when a VM is plugged into the Neutron port.
Alternatives
There are no alternatives to leverage the native GBP API in ODL.
Data model impact
None, as this change is simply adding support for new API extensions.
REST API impact
The ODL policy driver will have support for the new GBP API extensions added.
Security impact
None.
Notifications impact
None.
Other end user impact
Users deploying OpenStack with the Group Based Policy extensions will be able to utilze these new APIs in conjunction with the Helium version of OpenDaylight.
Performance impact
No change here.
Other deployer impact
To utilize the GBP APIs with OpenDaylight, the following versions of software are required: * Neutron: Juno * OpenDaylight: Helium
Developer impact
None.
