Add quizzes to every section

Many sections of lectures have 1-2 quizzes to help solidify learning, but there are also many sections without quizzes. Let's fix that. Add quizzes to these sections:

• [ ] 1 Quick Start
• [ ] 3 The Best Way to Setup Docker for Your OS
• [ ] 15 Your first pods
• [ ] Inspecting Kubernetes Resources (forthcoming)
• [ ] 16 Exposing Kubernetes Ports
