Create a blog-post about VM image builds

• [ ] Describe all the steps needed to be covered (when done manually) so we can compare that with Packit's automation.
• [ ] Describe the usage via Packit (with screenshots) for people that do not know Packit
• [ ] Publish to developer portal

I'm unassigning myself as I won't have bandwidth to do this, sorry :/

Since this is meant to be used by customers with development subs, we should register as such on console.redhat.com

I propose this structure for the blog post.

Title: Customize AWS cloud images with Image Builder and Packit

1. Packit intro
   • install the app, get approved
   • set up RPM builds and VM image build
   • verify it works, show how to install those RPMs
2. console.redhat.com
   • create a new account using the developer sub
   • pair with AWS
3. Choose project: ideally something that can be demonstrated in the terminal, our hello-world is a good candidate
4. Create a PR with a change (i.e. change terminal color of "world" output)
5. kick off vm_image_build
   • inform them the image can't be accessed in their console.rh.c
   • it's shared with AWS
6. go to AWS, create EC2 instance, verify
