Automated Security Assessment Chapter

**Is your feature request related to a problem? Please describe.**
Customers want to identify security vulnerabilities as well as deviations from security best practices in applications, both before they are deployed, and while they are running in a production environment.

**Describe the solution you'd like**
Adding a chapter focused on Amazon Inspector. We want to make it easy to build Inspector assessments right into the existing DevSecOps process, decentralising and automating vulnerability assessments.

**Describe alternatives you've considered**
Amazon Detector - hard to integrate as per a pipeline.
