[QA] The case for security test scenarios

Hi Sherif, I agree with everything you put here! I put the groundwork for
this into the Security_for_developers/Architecture. New features should
have Selenium tests for security critical features, and I would really like
to setup exactly the scenario you proposed, having automated regression
testing with Zap. I've just lacked the time to do it yet.

+1 on static analysis too. I tested checkmarks earlier this year and their
php 5.3 support wasn't good enough to give good results on our codebase.
I'm trying to get coverty setup right now. Both are closed source so I
don't like using them. Facebook's pfff has a lot of potential, but doesn't
do security testing yet, and we don't have ocaml expertise to help them
implement it.

So yes, I would love help! Let's get in touch next week and see if we can
get you setup to help us implement the dynamic testing part. Feel free to
ping me of list or on irc.
