The Windows image is quite large (about 20GiB), hence it takes some time
to copy it for every test in order to avoid potential corruption.
One way to mitigate that without compromising on safety between each
test is by using device mapper. By creating a read-only base, we ensure
the image won't be modified by any of the tests, and by creating one
snapshot for each test, we avoid copying the entire image each time.
A dedicated Copy On Write disk image is created to handle any change
that might be performed on the base image, letting the tests behave as
expected.

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

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

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.

command line by removing any occurence of "console=ttyS0" from it.

Many of the tests attempted to SSH into the VM and then run "shutdown"
but don't actually check that the VM has shutdown correctly and proceed
to kill the child process. Remove the associated SSH commands and sleeps
from those tests that are not explicitly checking the shutdown
behaviour.

Only some tests require the output for the tests to be captured so
default to not capturing the output to a pipe and instead make it
controllable.

Many of the tests use an identical network configuration. Add a
GuestCommand::default_net() to generate this configuration and use it
wherever possible.

Many of the tests use an identical disk configuration. Add a
GuestCommand::default_disks() to generate this configuration and use it
wherever possible.

This is a thin wrapper over std::process:Command which currently only
specifies the default binary but in future will handle more default
behaviour.
