Add Objectives for Each Play in Playbook

[tohch4]

As a Flexion security engineer, to more specifically implement each play in the playbook, I would like to extend the playbook (from #3) for each play to have a checklist of recommended, actionable objectives, like 18F's playbooks, such as this one.

@tdonaworth I was suggesting when we start working on shift-left materials, we organize under under topical playbooks we build out from the main one you approved in #3 and I think we should flesh those out. :-)

Tim is going to start by adding guidance around early scanner integration with IDEs and developer-centric security scanning early in the process, connecting it back to Playbook items around 3, 4, and 5, after conversation this morning.
