FWaaS (snaiksat): API/model review still in progress (https://review.openstack.org/#/c/29004/). I added some more unit tests but I need to add more per the review comments. Some review comments by Eugene on DB need to be addressed and some others from Oleg (I am currently on PTO haven't gotten to these yet). Rajesh Mohan is making progress with the IPtables driver, he has started writing code but has to do more work before posting a patch. He also needs the agent code from me, which I will be making available shortly.
