Issue #3: Adds initial setup for aks cluster on Azure

[SonOfLope]

This PR is allowing an aks cluster to be created with admin access given to defined ad_groups variable.
It aims to achieve the following :

• : Provide a reusable module for kubernetes allowing deployment in different regions.
• : Provide a reusable virtual network allowing separation of concerns and reusability.
• : Creates a staging aks cluster for the team.

I'm not entirely sure that I could get started deploying my own kubernetes cluster from the README.md. How could we get this to the point where anyone can create a kubernetes cluster on Azure free credits? Also getting queueing someone from Microsoft to review. Can be done in a future issue.

@SonOfLope ...also the description checklist has no checkmarks.

looks very clean, nice naming.

I added some information in README.md. Currently since we use Devops Azure for the pipeline it would not be an ideal set up for someone to try it so I will open an issue for it and hopefully by then we are no longer using Azure Devops.
