[EPIC] Provide example for third party dev kubernetes tools

[csantanapr]

Developers targeting Kubernetes often use tools that allow them to easily run, deploy, debug and live-reload their code while working with Kubernetes locally or remotely.
Most of the time first-time developers using Kubernetes would use minikube.

The following Epic is to create examples that Knative can be used by those developers using their Kubernetes tool of choice.

This will improve the user experience for those developers using Kubernetes and trying to add knative to their current Kubernetes solutions.

This idea comes from conversations with users at KubeCon NA (Oct 2021) hallway track, as I showed demos of knative user kept asking if it would work with Kubernetes tool x, like okteto or telepresence

In this category of tools are:

• Provide knative examples using skaffold #51
• Provide knative examples using tilt #52
• Provide knative examples using okteto #53
• Provide knative examples using telepresence #54

Examples should provide more than one language (nodejs, python, java, go)

One thing to discuss is where do we keep the examples, do we put them in docs repo under code samples, or create a knative-sandbox repo. I"m leaning towards sandbox repo

[csantanapr]

It would be good to get the examples once working review by the tools' open source project, they might have feedback, they might want us to post to their blog, and share with their community.

There is also the possibility for the tools open source project to have examples repo for their tool and adding a knative example would be easy to add.

We would need to add to the site the existence of these examples

I have small prototype using nodejs and skaffold for a demo I did for a conference here https://github.com/csantanapr/ato-2021

The idea is to add other languages like python, java, and go using ko. skaffold recently added ko support
