Create integration and smoke tests for the platform.

[apburnes]

To monitor the platform is operating as expected continuously and between deployments, implement integration and smoke tests.

Background

Build out a framework to do this in Concourse - post SCR?

• [ ] High resolution liveness checks DURING deployments, particularly proxy, webhooks, etc
• [ ] post-deployment smoke tests for various apps
• [ ] Run Zap scans against staging and production site urls after updates to any of the supporting component/infra repos.
• [ ] New Relic pings for every custom domain
• [ ] Deploy starter templates to verify they build and publish as expected with every platform deployment and change in the starter

Added Zap scanning for sites after discussion with GSA IT Sec.
