3b43551d98 ci: Use device mapper to avoid copying Windows image
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.

Fixes #2155

c3df42d42f ci: Copy Windows image for each integration test
By relying on the Guest object, Windows dedicated tests copy the Windows
guest image before booting from it. The point being to avoid corruption
between multiple tests. This is already how the rest of the integration
tests work, Windows tests were the only ones missing this feature.

5881809126 tests: Update integration tests to use new image without pollinate
This image does not have the pollinate service which can sometimes fail
and prevent SSH from starting as it marks itself as a prerequisite. This
service will never fully succeed as it tries to make a network
connection which will fail inside our test VMs.

a4c076bd09 tests: integration: Don't always have kernel serial output
When doing a direct kernel boot only have console=ttyS0 in the command
line if we are explicitly testing the serial output. The default
behaviour is `--serial null` so this output will not be visible but will
trigger a KVM exit for every byte which is very costly when running
under nested virtualization.

d598341534 tests: Add Windows guest integration test
This is a new integration test running Windows as a guest with Cloud
Hypervisor. Once the VM is booted, the test connects to the guest
through SSH and shutdown the VM. If this succeeds, this means the VM
was properly booted to userspace and that the network was functional.

Important to note that because this test generates lots of logs, it
requires a large pipe size for both stdout and stderr.
