Generators in kubectl are deprecated #34

Kubernetes has deprectated generators in `kubectl run` in version 1.18.

https://kubernetes.io/docs/setup/release/notes/#deprecation-4

Remove all the generators from kubectl run. It will now only create pods. Additionally, deprecates all the flags that are not relevant anymore.

This affects the sections:

Intro
- kubectl run nginx --image=nginx --replicas=3
Validation and generators
- To construct the HTTP request, kubectl uses something called generators which is an abstraction that takes care of serialization.
API groups and version negotiation
- After kubectl generates the runtime object
etcd
- (kinda like the inverse process of kubectl's generators)

And that's all I could find with some grokking.
