Add the ability for cloud-hypervisor to create, manage and monitor a
pty for serial and/or console I/O from a user. The reasoning for
having cloud-hypervisor create the ptys is so that clients, libvirt
for example, could exit and later re-open the pty without causing I/O
issues. If the clients were responsible for creating the pty, when
they exit the main pty fd would close and cause cloud-hypervisor to
get I/O errors on writes.
Ideally the main and subordinate pty fds would be kept in the main
vmm's Vm structure. However, because the device manager owns parsing
the configuration for the serial and console devices, the information
is instead stored in new fields under the DeviceManager structure
directly.
From there hooking up the main fd is intended to look as close to
handling stdin and stdout on the tty as possible (there is some future
work ahead for perhaps moving support for the pty into the
vmm_sys_utils crate).
The main fd is used for reading user input and writing to output of
the Vm device. The subordinate fd is used to setup raw mode and it is
kept open in order to avoid I/O errors when clients open and close the
pty device.
The ability to handle multiple inputs as part of this change is
intentional. The current code allows serial and console ptys to be
created and both be used as input. There was an implementation gap
though with the queue_input_bytes needing to be modified so the pty
handlers for serial and console could access the methods on the serial
and console structures directly. Without this change only a single
input source could be processed as the console would switch based on
its input type (this is still valid for tty and isn't otherwise
modified).

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.

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.

When an SSH command fails we want to be able to see, via a panic() why
and where it failed. Replace use of .unwrap_or_default() from SSH
command calls to ensure that we can see the location of the panic.
Also enhance the existing SSH output code to show the error if there is
one.

The boot time for direct kernel boot based tests is significantly
quicker than booting via the firmware and stock kernel as it triggers a

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.
