✨ feat: Add nestri cli (#79)

## Description

**What issue are you solving (or what feature are you adding) and how
are you doing it?**


We are adding an option to start the Nestri server (omg almost called it
Netris :) using a cli

The idea is to reduce the friction of starting up the service and
running it, this includes:
1. Installing and configuring the Windows executables for the game
2. Running the game on a linux machine
3. Preparing the host system i.e configuring Docker, Nvidia
{Drivers,CUDA} etc etc
