This commit extends the existing test_vfio by hotplugging an extra
virtio-net device to the L2 VM. The test for validating the hotplug
succeeded is the same as the one to verify the non-hotplugged devices.

A new ClearLinux image has been uploaded to the Azure storage account.
It is based off of the ClearLinux cloudguest image 31310 version, with
three extra bundles added to it.
First bundle is curl, which adds the curl binary to the image, second
bundle is iperf, adding the iperf binary to the image, and third bundle
is sysadmin-basic to include utility like netcat.
The image is 2G in size.

When the CI runs in a brand new VM, there's no problem with the validity
of the images as they just got downloaded from the Azure bucket.
In case of a user who runs the CI locally, while doing some debug, he
might provision the images with cloudinit at some point, and later try
to run the CI based on these same images. What happens is that the CI
might randomly fail because the provisioning will not happen again as
it already happened.
This patch ensures the CI to fail early and show an error message to
notify the user about the validity of the images, based on their
sha1sum.

Virtio-fs maintainers recently updated the virtiofsd daemon through
their official branch on Gitlab. It includes fixes that were needed for
cloud-hypervisor to work correctly with it.
Jenkinsfile needs to be updated since the virtiofsd build requires both
libseccomp and libcap-ng to be present on the system.
One thing to notice, because the latest branch introduced a change
regarding libfuse behavior, the counterpart patch has been added to the
custom kernel branch "virtio-fs-virtio-iommu".

The setcap tool is unusual in its behaviour in that it will process each
parameter separately and abort if one of the parameters is invalid (e.g.
after a symlink.) But any previous parameters will be correctly
processed. This means that depending on the generated test binary name
an invalid entry might occur before it and thus abort the setcap.
Fix to only setcap on the test binary by excluding the other files.
Because the binary name is based on a hash the PR that introduced this
version worked but once merged the hash changed and broke the build.

In order to validate the new virtio-fs daemon written in Rust is
behaving correctly, a new integration test has been added. Important to
note that for now, only a test with cache=none and dax=off can be added
since the daemon does not support shared memory region yet.
The long term goal being to replace virtiofsd with vhost_user_daemon
once it will reach parity regarding the supported features.

The virtiofsd daemon takes a bit of time creating and listening on the
socket. By adding 10s timeout, we make sure the vhost-user socket has
been properly created before the VMM tries to connect to it.
Also, the daemon needs cap_dac_override capabilities to access debugfs
filesystem.
Last thing, both virtio-fs and virtio-pmem tests were slightly different
from the others since they were not explicitly killing cloud-hypervisor
and virtiofsd processes once the test was done.
