Investigate using njs library as a replacement for lua/openrusty

[strongjz]

This issue is tracking community questions around using the nginx library njs as a replacement for lua/openrusty

There are many pieces of functionality tied to the lua/openrusty library. This ties ingress-nginx to a specific version of nginx that openrusty libraries support.

We have had a plethora of asks to upgrade our version of nginx to a supported/modern version; we currently are at 1.21.

Moving to njs will offer the ability to do so but with great cost and effort, so we are asking the community for feedback.
