Need a way to validate custom AMI images

[dims]

When folks customize their AMI(s) it would be good to have some way to validate that they haven't broken any expectations of the maintainers of this repository ( with a basic sanity/sniff test). This will possibly help reduce the time to iterate trying each change over and over again.

For example, in the upstream CAPI project called image-builder, they use a tool called goss:

• https://github.com/goss-org/goss

Here's their readme/howto:

• https://github.com/kubernetes-sigs/image-builder/blob/master/docs/book/src/capi/goss/goss.md

Here's a quick search of that codebase:

• https://github.com/search?q=repo%3Akubernetes-sigs%2Fimage-builder%20goss&type=code

Here's an example where they check for some kernel parameters are set correctly:
