Setting permissions in the _cloud_init.yml playbook which was called at
the end of the cloudinit playbook caused the ACLs on the home directory
to change its mask, making the directory inaccessible.

This will help reduce spatial overhead of having multiple copies of the
virtual machines in both the output and vms directories.

Slower systems may have issues receiving all inputs with the faster key
rate. This should only delay the process by a couple of seconds at most,
so it should not affect things in a measurable way.

Install kali as an optional cloud-ready image. The Makefile rules will
build the optional image(s) only when explicitly mentioned (i.e., the
`make` command has the `optional` parameter), because the `all` rule
does not list them.

Some of the images did not correctly configure the hostname as part of
the installation process. These changes force setting the hostname when
the ansible post-installation step runs.

Removing /tmp causes a "device busy" error in some cases, resulting in
failed playbooks. The tmp directory should be mounted as a tmpfs
filesystem on modern systems, and should consequently not persist
information across reboots, so this change should not alter the regular
functionality.

Unattended upgrades makes installing new packages hard since it attempts
to upgrade all packages on the system; if the VM image is a few months
old, the upgrade process is slow since it must upgrade a large number of
packages.

NOTE: Of course, this means that security updates are not installed
either, so users must make sure to update the system periodically.

The swap image used valuable space on the virtual machine's disk, which
meant that in some specific cases where the disk was small (e.g., 16GB),
the system would run out of disk space. This caused a common issue in the
NFS lab, since it uses multiple disks for the nested virtual machines,
which quickly fill the space.

We also remove the `e` that was tied to the `-i` parameter in `sed`
commands, as that was interpreted as having to create a backup file with
`e` appended to the original file's name (e.g. `/etc/defaults/grub`
would be backed up as `/etc/defaults/grube`).

The first disk is always `vm-name.qcow2`, and auxiliary disks are
`vm-name-1.qcow2`, `vm-name-2.qcow2`, and so on. This allows sorting the
disks using version sort, with the main disk being first in the list.
This is required to make sure the VM boots from the main disk.

Centos Stream 8 appears to no longer provide signed checksums, and the
lifecycle of the Stream versions has been shortened greatly. We move to
the longer supported Alma Linux 8 that is starting to be adopted more
widely in the industry, similar to Rocky Linux.
