Refactor network API

https://blueprints.launchpad.net/nova/+spec/refactor-network-api

To have a common API network base with all required methods so neutron / nova network api can inherit from.

Problem description

Right now network api’s do not inherit from a common base, and if the functionality is not implemented developers may forget to add the method. The situation is that every time that functionality want to be accessed from the API an exception is thrown due to missing methods and not clear error is returned.

Proposed change

The idea is to create a network_base API that define all the possible methods and just throw NotImplementedError, so next time the user will see the proper error message.

Also fields like sentinel object could be directly inherited in the base api.

Alternatives

The current way to do this is to manually add the missing methods to neutronv2 api for instance. Every time someone add a new method to one api has to do the same for the others and raise NotImplementedError if not supported.
