[cprivitere]

User Story

I would like kubectl and crictl to be configured by default on machines created by CAPP. This will aid in debugging, testing, and troubleshooting.

Detailed Description

Set up the following:
Default kubeconfig for root
alias k=kubectl
Set up default crictl container runtime environment variable
enable kubectl and crictl autocompletion

/kind feature

Consider adding more tools that most people expect / commonly use.

Also, are any of these suggestions risky from a security perspective?
