This patch introduces the model and extension
framework for implementing distributed virtual
routing on top of Open vSwitch.
A new admin-only 'distributed' (as opposed to a
'centralized' or legacy-mode) attribute is added
to the API router resource. It is possible to convert
an existing (centralized) router to a distributed
one; the opposite conversion, even though allowed by
the API, may not be honored by the underlying
plugin implementation and an appropriate error will
be reported.
When creating a router (regardless of the user role),
Neutron will rely on a system wide configuration, whose
default currently allows to create 'centralized' routers.
Tests are added for basic unit coverage; when the first
building blocks for neutron-testing-refactor
are complete, functional testing will be added.
This is because we should be moving away from how
extension tests have been done up until now.
