[Story]: Unprivileged/non-root NGINX deployment on k8s & openshift

Overview

As a user I want to run NGINX Plus in my Kubernetes and Openshift clusters as an unprivileged/non-root ("regular", non-ingress) pod. I'm expecting to get all fully documented steps to achieve that.

Which product or products does this request relate to?

NGINX Plus

Description

Documentation currently provides details and steps to run NGINX Plus on docker (https://docs.nginx.com/nginx/admin-guide/installing-nginx/installing-nginx-docker/) but there's nothing when the target infrastructure is kubernetes (or Openshift, which is common across EMEA).
Additionally, when deploying on Openshift, customers often have to comply with unprivileged uid and gid numbering (see https://www.redhat.com/en/blog/a-guide-to-openshift-and-uids).
The new documentation section should provide a full walkthrough allowing the user to:

• either pull a pre-built NGINX Plus "non-root" docker image from the F5 private registry or build a docker image based on a Dockerfile (for instance https://github.com/nginx/nginx-demos/tree/main/nginx/docker-image-builder). The docker image should optionally include the NGINX agent v2 or v3 and support unprivileged gid and uid
• provide sample manifests that can be used to deploy NGINX Plus on a Kubernetes or OpenShift cluster. The manifest(s) should support passing parameters to the NGINX agent in order to connect the NGINX pod to either NGINX Instance Manager or NGINX One Console

Acceptance criteria

As a user I want to be able to follow the documentation to deploy an unprivileged/non-root NGINX Plus pod in my Kubernetes and/or Openshift cluster. All steps should be fully described and I should be required to make only small modifications to the example manifests to get things up and running
