f449aec78e ci: AArch64: Enable AArch64 mmio-related integration test cases
This commit enables some mmio-related integration test cases on
AArch64, including:
* some vhost_user test cases
* virtio-blk test cases
* pmem test cases

Also this commit contains a bug fix in creating virtio-blk device.
Previously, when creating the FDT, the virtio-blk device was
labeled in the reverse order of address allocation.

8be80aca80 ci: Give some time to the disk hotplug
Under high load, the VM might take some time to hotplug the disk after
the hotplug command has been issued. For this reason, let's put a 10s
sleep before checking for the presence of the new disk.

802f02532a ci: Extend test_vfio time before VM is ready
We want to give the time to the nested VM to be fully ready before we
check it's correctly setup. This involves 3 layers of virtualization
when running the CI on Azure, which added to the high load happening
because of the parallelization, adds up to the start up time.

In order to differentiate tests that can be run in parallel versus
tests that must be run on their own, we move all tests into dedicated
modules.

The point is to avoid glitches in results that can be caused by the fact
that other tests (hence VMs) are running at the same time.

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.

ba4ec7fce2 ci: Extend snapshot_restore_test with hotplug
There's a simple way to trigger PCI BAR reprogramming for a given
device, by removing it and then hotplugging it back. The Linux kernel
will simply choose to place the BARs at different location than the ones
chosen by Cloud-Hypervisor. By doing so, and creating the snapshot after
this hotplug operation, we can manage to validate that the resource are
correctly restored for a given virtio-pci device.
