Unify delivery of openshift CLI and improve customer experience in maintaining life cycle of those CLI via Openshift CLI manager  **

Current state : Openshift CLI list and their delivery  mechanism 

Why we need a CLI Manager 

As the number of projects in openshift is increasing, so is the number of CLI’s associated with those projects . These CLI’s are not bundled with Openshift payload and made available to be downloaded via RPM, Operators, cloud.redhat.com or Extract binaries. 

Example in Openhsift https://docs.openshift.com/container-platform/4.11/cli_reference/index.html We have listed 5 CLI and each CLI has its own documentation page .Each CLI has its own download location and different ways of installing them on linux and windows . 

Imagine in a few years if that list grows to 10 or 20 CLI then how are we going to manage ? 

Persona 1 : Openshift administrator 

How Openshift CLI Manager will make openshift admin( user of CLI)  life easy 

As an Openshift admin i don't have to worry about 

1. How to discover list of openshift CLI that i can download 
2. Where to install them
3. Maintain life cycle of those CLI (upgrade/delete)

Persona 2 : Openshift CLI developer  

How Openshift CLI Manager will make CLI developer life easy 

As a CLI developer I don't have to worry about how to deliver my CLI to the customer via RPM, Operators, cloud.redhat.com or Extract binaries ?

Example if i am ROSA cli developer i don't have to worry about

1. Listing CLI based on OS type on cloud.redhat.com 
2. Provide 4 page instruction to use on how to download https://docs.openshift.com/rosa/rosa_cli/rosa-get-started-cli.html 

Just go to  https://github.com/openshift/krew-index and 

1. Write a Krew plugin manifest file.
2. Tell you customer to run oc krew install ROSA CLI
