In our build-script (build.rs), we won't set the environment variable
'BUILD_VERSION' when the 'git describe' command failed (e.g. when the
current source tree does not contain git information). This patch added
a fall back path where the default value of 'BUILD_VERSION' is based on
the 'cloud-hypervisor' crate version.

The goal of this commit is to rename the existing NUMA option 'id' with
'guest_numa_id'. This is done without any modification to the way this
option behaves.
The reason for the rename is caused by the observation that all other
parameters with an option called 'id' expect a string to be provided.
Because in this particular case we expect a u32 representing a proximity
domain from the ACPI specification, it's better to name it with a more
explicit name.

Based on the recent changes regarding how to describe NUMA nodes to the
guest, the documentation related to memory zones and NUMA has been
updated accordingly.

Since both --memory-zone and --numa parameters have been updated with
addition and removal of multiple options, this commit updates the
related integration tests to ensure they are still valid.

The way to describe guest NUMA nodes has been updated through previous
commits, letting the user describe the full NUMA topology through the
--numa parameter (or NumaConfig).
That's why we can remove the deprecated and unused 'guest_numa_node'
option.

Based on the previous changes introducing new options for both memory
zones and NUMA configuration, this patch changes the behavior of the
NUMA node definition. Instead of relying on the memory zones to define
the guest NUMA nodes, everything goes through the --numa parameter. This
allows for defining NUMA nodes without associating any particular memory
range to it. And in case one wants to associate one or multiple memory
ranges to it, the expectation is to describe a list of memory zone
through the --numa parameter.

This new option provides a new way to describe the memory associated
with a NUMA node. This is the first step before we can remove the
'guest_numa_node' option from the --memory-zone parameter.

Now that we have an identifier per memory zone, and in order to keep
track of the memory regions associated with the memory zones, we create
and store a map referencing list of memory regions per memory zone ID.

In anticipation for allowing memory zones to be removed, but also in
anticipation for refactoring NUMA parameter, we introduce a mandatory
'id' option to the --memory-zone parameter.
This forces the user to provide a unique identifier for each memory zone
so that we can refer to these.

This patch ported many tests to the new methodology, where the guest log
will be printed only when the test is failing.
Things to finish in follow-up PRs:
1. Special tests not ported yet include: test_reboot,
test_bzimage_reboot, test_serial_null(), test_serial_tty(),
test_serial_file(), test_virtio_console(), test_console_file(),
and test_simple_launch.
2. Few direct calls to 'Command::new(clh_command("cloud-hypervisor"))',
which is still printing the guest console
