Decouple networking-ovn from neutron via neutron-lib

Registered by Boden R on 2017-02-28

This is a continuation of the neutron-lib saga.

While our initial work in [1] laid a foundation for neutron-lib's future by plumbing out the approaches/processes/implementations/etc., as discussed at the Pike PTG we need additional neutron-lib BPs that are containable within a single release.

The new approach for tracking neutron-lib work is to create a BP for a target sub-project and use the BP track the rehoming of that sub-project's neutron dependencies to neutron-lib + consume them. The BP is closed once the sub-project it targets no longer depends on neutron, but neutron-lib instead.

This BP targets the networking-ovn project and includes the work to:
- Rehome networking-ovn's neutron dependencies to neutron-lib (refactoring as needed).
- Release them via neutron-lib pypi package.
- Consume them in networking-ovn, thereby removing the respective neutron dependency(s).

We are also tracking the networking-ovn neutron dependencies and their status in a google sheet [3]. Please see the sheet for finer grained details.

For details on the rehoming process, please see [2].
