Subject: [PATCH 3/4] ovs: fix state=ignore for ovs port when removing them

When removing an ovs port while the interface is marked as ignored, the
interface should not being removed from the ovs bridge as the user
specidied it should be ignored.

Example:

```
interfaces:
- name: dummy0
  type: dummy
  state: ignore
- name: ovsbr0
  type: ovs-bridge
  state: up
  bridge:
    port:
    - name: ovs0
```

Integration test case added.
