Use Case Guide: How to direct traffic to your application via NKG

[mpstefan]

As a potential user of NKG
I want a guide to help me understand how I can host a one application API with NKG
So that I can easily understand how to immediately start using NKG in my environment.

Acceptance

• A guide is created that explains how a user may set up their single application that hosts an API with NKG.
• The guide explains WHY each step is necessary and how it can be tailored to their own use case.
• The guide mentions forwarding "REST API" and "web application" traffic for search engine optimization.
• A link is present for any relevant Kubernetes Gateway API guide.

Here's a super rough outline I have...

More conceptual, WHY do we need a gateway, WHY do we need a route?
