This commit creates a new binary target for generating performance metrics,
and also adds a set of performance tests for network throughput/latency,
block I/O performance, and boot time.

With enabling the `vendered-openssl` feature, we can now cross-build the
`test_infra` crate for "musl" and "aarch64" targets. In this way, we
can remove the `test_infra` crate from the "exclude" list, so that this
crate can be checked and processed by "cargo clippy" and "cargo fmt".
More details can be found: https://docs.rs/openssl/latest/openssl/#vendored
As 'musl-gcc' is required, this commit also installs the `musl-tools`
package for our "build" github action on the musl target [1].

By having the DeviceNode storing a PciBdf, we simplify the internal code
as well as allow for custom Serialize/Deserialize implementation for the
PciBdf structure. These custom implementations let us display the PCI
s/b/d/f in a human readable format.

As we've added support for cold adding devices to a VM that was created
but not already started, we should propagate the `204` response
generated on those cases to the yaml file, so openapi-generator can
produce the correct client code on the go side, to handle both `200` and
`204` successful results.

Instead of erroring out when trying to change the configuration of the
VM somewhere between the VM was created but not yet booted, let's allow
users to change that without any issue, as long as the VM has already
been created.

Since the devices behind the IOMMU cannot be changed at runtime we offer
the ability to place all devices on user chosen segments behind the
IOMMU. This allows the hotplugging of devices behind the IOMMU provided
that they are assigned to a segment that is located behind the iommu.

Introducing a new integration test relying on the virtio-balloon ability
to free host pages that have been reported as freed by the guest.
This test checks that after consuming a lot of RAM in the guest, the VMM
process is able to releases the pages reported by the guest. Simply done
by checking the RSS associated with the VMM's process follows the memory
trend in the guest.

Implement the VIRTIO_BALLOON_F_REPORTING feature, indicating to the
guest it can report set of free pages. A new virtqueue dedicated for
receiving the information about the free pages is created. The VMM
releases the memory by punching holes with fallocate() if the guest
memory is backed by a file, and madvise() the host about the ranges of
memory that shouldn't be needed anymore.

Adding a new parameter free_page_reporting=on|off to the balloon device
so that we can enable the corresponding feature from virtio-balloon.
Running a VM with a balloon device where this feature is enabled allows
the guest to report pages that are free from guest's perspective. This
information is used by the VMM to release the corresponding pages on the
host.

In order to allow for human readable output for the VM configuration, we
pull it out of the snapshot, which becomes effectively the list of
states from the VM. The configuration is stored through a dedicated file
in JSON format (not including any binary output).
Having the ability to read and modify the VM configuration manually
between the snapshot and restore phases makes debugging easier, as well
as empowers users for extending the use cases relying on the
snapshot/restore feature.
