Improve control plane performance of the Port deletion flows

Registered by Antoni Segura Puimedon on 2017-09-22

We need to speed up a lot the performance of the time between the Pod being marked deleted in the Kubernetes API and CNI returning with the port already deleted.

This implies two things:
- Return used ports as quickly and cheaply as possible to the pool if pools are in use.
- Reduce the work and calls done in the CNI side (Possibly caching the data about running vifs in the worker node fs).
