Gary Kotton b6cb4316da Ensure unique mac address allocation.
This is the first part of bug 1008029

If the port command does not contain a MAC address then Quantum will generate
a random MAC address. The mac address will be saved in the database to ensure
that it is not used by another port on the same network.

Added mock-based test for mac exhaustion.
