migrating(eks): add example of migrating node groups with zero downtime

[metral]

Adding a condensed example of the pulumi/eks e2e test.

This example is related to the tutorial & blog post:

• Tutorial PR: migrate(eks): add tutorial of migrating node groups with zero downtime docs#1327
• Blog Post PR: migrating(eks): add blog post of migrating node groups with zero downtime docs#1328

Also, refactor assertHttpResultWithRetry() to accept HTTP headers.

Hi @metral

I left a few comments - nothing crazy - one thing to note - I think we need to link to the blog post so that users know how to run the example. It kinda breaks the other convention of the README having step by step instructions - but that would be duplicated effort :)

LGTM!

You're right. This one is tricky given that the tutorial is the step-by-step instructions here per the unique scenario. I'll open a PR to link the tutorial steps here once the tutorial PR is merged.

Sounds good to me! :)
