Providernet Extension support for Nuage Plugin

https://blueprints.launchpad.net/neutron/+spec/providernet-ext-support-for-nuage-plugin

Adding provider-network extension support to existing nuage networks’ Plugin

Problem description

Current Nuage Plugin does not support Neutron’s providernet extension. Nuage’s VSP supports this feature and the support for extension needs to be added in the plugin code.

Proposed change

Adding extension support code in Nuage plugin.

Implementation

The provider extended attributes for networks enable administrative users to specify how network objects map to the underlying networking infrastructure. This fits well with Nuage’s ability to map the overlay with the underlay provided option. There will not be a significant change in the plugin behavior. When the network is created with provider options enabled, segments information (id, physical_network, vlan_id) is passed to the Nuage’s backend and it will be acted upon. Backend will either accept it or will fail the request and the response will be relayed back to the user. In case of a failure, resource operation in neutron will also fail. In Juno, we want to keep the implementation most basic.
