Booting Desktop and server live installer ISOs comes with different
platform requirements. When running kvm-test, we now accept the name of
a profile via the --profile option.
Profiles provide default settings for memory, disk size and extra QEMU
options. For now, two profiles are hard-coded: "server" - which is the
default and "desktop".
For desktop, we use two vCPU, 8 GiB of RAM, a 20 GiB disk and pass the
-device qxl option.

When invoking kvm-test.py, one can pass the --with-tpm2 option so that
we emulate a TPM and make it available in the guest.
This requires the swtpm package which is available in jammy and more
recent versions of Ubuntu.

The --cloud-config option now replaces the old --autoinstall-file
option.
The use of --autoinstall-file always made kvm-test pass the autoinstall
argument to the kernel command line. With the --cloud-config option, we
now determine if the autoinstall argument is needed by reading the cloud
config and checking if an autoinstall section is present.
The two new options --force-autoinstall and --force-no-autoinstall can
be used to override this behaviour.
The --autoinstall option is also dropped. If we want to use the default,
hardcoded cloud-config, one can use --cloud-config-default.
This can be useful to ease debugging of the VM using a config that looks
like:
#cloud-config
users:
- default
- name: root

The only way we had to pass -nic options to QEMU was to specify the
number of networks using the --nets option. Depending on its value, the
option would instruct QEMU to:
* instantiate *n* user host networks if --nets >= 1
* instantiate no network if --nets is 0
* instantiate a "dead" network if --nets < 0
To simulate more advanced networks (such as networks where HTTP proxy is
needed), we want to add the possibility to use TAP network interfaces.
This patch adds the ability to pass custom -nic options to QEMU.
Three new options are available:
* The --nic option passes the argument as-is to QEMU -nic option
* The --nic-user option passes a user host network -nic option to QEMU
- with SSH forwarding enabled. This is just like we do when using the
--nets >= 1 option)
* The --net-tap takes the name of an existing tap interface and
generates the following -nic argument:
tap,id={ifname},ifname={ifname},script=no,downscript=no,model=e1000
In the example below:
* the first network uses the tap0 interface.
* the second network uses the tap1 interface (it is syntactically
equivalent to the first one)
* the third network uses a user host network (with SSH forwarding)
$ kvm-test.py \
--nic tap,id=tap0,ifname=tap0,script=no,downscript=no,model=e1000 \
--nic-tap tap1 \
--nic-user

Passing --use-fuse to scripts/kvm-test.py allows to run as non-root.
It requires installation of the package fuseiso so the switch is
disabled by default.

Since 06ac3f92, we invoke kvm directly through subprocess.run.
Therefore, we must not add extra quotes around the -append options,
otherwise they persist and are passed in the kernel command line:
$ cat /proc/cmdline
"autoinstall subiquity-channel=stable" initrd=initrd
Later on, we fail to parse "autoinstall" and "subiquity-channel=stable"
as two distinct options.

The function drive() used to return a string in the following format:
"-drive file=/path/to/iso,..."
However, qemu/kvm expects "-drive" to be an argument and
"file=/path/to/iso,..." to be another argument.
The command was constructed as below since the beginning:
kvm = [
"kvm",
"-cdrom", "custom.iso", # <- OK
"-drive file=/path/to/iso,...", # <- NOK
]
Before 06ac3f92, we would join all the arguments using spaces before
executing the kvm command. Therefore we would luckily end up with a
correct command:
" ".join(kvm) -> "kvm -cdrom custom.iso -drive file=/path/to/iso,..."
However, now that we supply the command to subprocess.run directly, the
problem shows up.
Fixed by returning a tuple("-drive", "file=/path/to/iso,...") from
the drive() function.

* fix several syntax errors
* missing 'this' item was renamed to 'iso'
* change the simulated 'bash -x' output to stderr
* use shlex functions for join/split
