Update firmware WD Black SN770 firmware on Arch Linux

Been having problems with my new SN770 drive, and decided to check if I can firmware update it on Linux. WD only provides a Windows tool, Western Digital Dashboard to download and install firmwares, but, it's possible to find the firmware and install it using Linux tooling as well.

1. Check that `nvme-cli` is installed:

❱ sudo pacman -S nvme-cli

	#!/usr/bin/env bash

	set -e
	set -u

	## Variables
	set_vars(){
	APT_MIRROR_HOST="mirror"
	LXDKVM_SSTREAM_HOST="mirror"
	JUJU_SSTREAM_HOST="mirror"

	NO FEATURE
	NODES=3ctlr_2comp_3ceph
	# modify the ceph nodes memory to 5GB at config/nodes/3ctlr_2comp_3ceph.yml
	control_memory: 8192
	control_disk: 45
	compute_memory: 5120
	compute_disk: 50
	ceph_memory: 5120
	ceph_disk: 55
	undercloud_memory: 12288

	#!/bin/bash

	virsh net-destroy kimgtnet0
	virsh net-start kimgtnet0
	virsh net-destroy kimgtnet1
	virsh net-start kimgtnet1

	VMS=$( virsh list \| grep '-' \| awk '{ print $2; }' )

	for guest in $VMS ; do

	using System;
	using System.IO;
	using System.IO.Compression;
	using System.Text;

	namespace TarExample
	{

	public class Tar
