6cd31e7a4d tests: Introduce new test methodology
Rather than using a credible TestBlock to capture the test assertions
instead use a catch_unwind block to catch the panic and turn
it into a Result<>.

If block panicked or the child binary had non-zero exit then, and only
then, print out the child output.

This results in a clearer test output with no interleaving.

Currently only test_counters is ported to this methodology to
demonstrate its use.

c2920d2b6b ci: Move from Clear Linux to Ubuntu Focal Fossa cloud image
Move the CI to rely entirely on Ubuntu cloud images. It's worth noting
that both QCOW2 and RAW images from Ubuntu Focal Fossa have been
modified to include the tools needed from integration tests.
This means fio, iperf, iperf3, netcat and socat have been added to the
image. The snapd package have been fully removed as it was expecting the
support for squashfs (not present when using our own kernel from direct
kernel boot), which was causing some failures, and was preventing
cloud-init from terminating properly.

4b64f2a027 vmm: cpu: Reuse already allocated vCPUs if available
When a request is made to increase the number of vCPUs in the VM attempt
to reuse any previously removed (and hence inactive) vCPUs before
creating new ones.

This ensures that the APIC ID is not reused for a different KVM vCPU
(which is not allowed) and that the APIC IDs are also sequential.

The two key changes to support this are:

* Clearing the "kill" bit on the old vCPU state so that it does not
  immediately exit upon thread recreation.
* Using the length of the vcpus vector (the number of allocated vcpus)
  rather than the number of active vCPUs (.present_vcpus()) to determine
  how many should be created.

This change also introduced some new info!() debugging on the vCPU
creation/removal path to aid further development in the future.

TEST=Expanded test_cpu_hotplug test.

9f2eddd9d8 ci: Fix test_serial_off
The integration test validating that --serial off works correctly was
not properly written as it was using the FW, which by default would use
the kernel command line found in the EFI partition. Unfortunately, this
kernel command line was including "console=ttyS0", which causes the
kernel to try to write to the serial port, even if there's no serial
port being emulated.

The problem is, when no emulation of the serial port is provided, the
default value returned on 0x3f8 is 0, which makes the guest kernel think
that some data needs to be read.

The only way to avoid all this is by ensuring we can control the kernel
command line by removing any occurence of "console=ttyS0" from it.
