chore: add kubectl equivalent examples

[Ananya2001-an]

Related to #1253
Created a kubectl/equivalents folder inside examples. Each file corresponds to the relevant kubectl command making it easier for users to understand the usage of the client. Makes it more readable and maintainable.

Current files added:

• Create namespace
• Create Namespace from yaml
• Create Namespaced pod
• List namespaces
• List Pods
• Create Resource quotas
• List all Resource quotas

... more to be added

Thanks for this PR! I think it would be even better to introduce a kubectl.js as part of this library, so that people can simply call the kubectl equivalents.

It would be similar to https://github.com/kubernetes-client/java/tree/master/extended/src/main/java/io/kubernetes/client/extended/kubectl

Yeah that sounds good! I will work on it. I think we can even add some tests for the same with jest, wdyt? But I would work on it in a separate PR to keep things simple for now :)

[Ananya2001-an]

Hey @brendandburns I created a Kubectl.ts file taking reference from the java client. Though, I am not very sure about how to create the generic execution calls for each function. Would like some help with that :) I have pushed the changes for your convenience.

[brendandburns]

Yes, you're right, there's no good equivalent of the generic client in Java. We should add that :)

If that's too much work, feel free to revert this PR just to the examples and we can merge those and work on the generic kubectl implementation some other time.

[Ananya2001-an]

I have reverted the changes, @brendandburns you can review now :)
