0223cf8c2b ci: Update ClearLinux image
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.

ad223f2b50 fs: Use cache=none by default
The cache= option from the virtiofsd backend is meant to be used
depending on how the user wants to use the guest page cache. For most
use cases, we want to bypass the guest page cache to reduce the guest
memory footprint, which is why "cache=none" should be the default.

"cache=always" is the other option when the user wants to do something
specific by using the guest page cache, but should not be the default
anymore.

5fc3f37c9b vmm: Add iommu=on|off option for --device
Having the virtual IOMMU created with --iommu is one thing, but we also
need a way to decide if a VFIO device should be attached to the virtual
IOMMU or not. That's why we introduce an extra option "iommu" with the
value "on" or "off". By default, the device is not attached, which means
"iommu=off".

One side effect of this new option is that we had to introduce a new

74a21f24e1 vendor: Remove vendoring
The cargo interaction with the .cargo/config does not meet our
requirements.

Regardless of .cargo/config explicitly replacing our external sources
with vendored ones, cargo build will rely first on Cargo.lock to update
its local source cache. If a dependency has been push forced, build
fails because of our top level Cargo.toml description.
This prevents us from actually pinning dependencies, which defeats the
vendoring purpose.

We're removing vendoring for now, until we understand it better.
