Script to create azure linux network, server, and minimega installer

[cbaxley]

🗣 Description

This creates the script to create a network and a ubuntu machine so we can run minimega on it.
It also creates the installer for minimega on that new ubuntu machine.

💭 Motivation and context

We will want to be able to run minimega from the pipeline so we can run all of our tests in the pipeline or
even from a local dev environment.

🧪 Testing

I was able to create the server and run the installer successfully multiple times from my local environment
