Peter Matulis 173f24482b Rewrite getting started

Rewrite the getting started pages by turning it
into an actual tutorial. This will be the main
Charmed OpenStack tutorial (golden path) for
people to follow.

It is hoped that once bundles in the Charmhub are
properly staged the need to download the bundle
repository will no longer be necessary.

Getting started

Overview

This tutorial will show how to deploy a Charmed OpenStack cloud with the use of a bundle and an overlay. The cloud's major elements are:

Ubuntu 20.04 LTS (Focal)
OpenStack Xena
Ceph Pacific

OpenStack services will include Compute, Network, Block Storage, Object Storage, Identity, Image, and Dashboard.

This is a test cloud that will be used by a single (admin) user.

Requirements

Hardware

You will need a MAAS cluster with four nodes:

1 x Juju controller node: 4GiB RAM, 2 CPUs, 1 NIC, 1 x 40GiB storage
3 x cloud nodes: 16GiB RAM, 4 CPUs, 2 NICs, 2 x 80GiB storage

Note

The smaller controller node can be targeted via Juju constraints at controller-creation time.

A single network interface is sufficient on the cloud nodes if an Open vSwitch bridge is set up in MAAS. See the MAAS page <cdg:install-maas> in the OpenStack Charms Deployment Guide <cdg:index> for details.

Software

The software versions used in this tutorial are:

Ubuntu 20.04 LTS (Focal) for the cloud nodes
MAAS 2.9.2
Juju 2.9.27

Other prerequisites

You should have Juju installed and be comfortable with its basic usage.
Create directory ~/tutorial as all tutorial files will be placed there.
The MAAS server must have Focal amd64 images available.
You should be briefly acquainted with these concepts:

Procedure

The procedure consists of the following steps:
