Add a hypervisor configuration to specify if IO should
be handled in a separate thread. Add support for iothreads for
virtio-scsi for now. Since we attach all scsi drives to the
same scsi controller, all the drives will be handled in a separate
IO thread which would still give better performance.
Going forward we need to assess if adding more controllers and
attaching iothreasds to each of them with distributing drives
among teh scsi controllers should be done, based on more performance
analysis.

If a container is not running, but created/ready instead, this means
a container process exists and that we can actually exec another
process inside this container. The container does not have to be
in running state.

In case a consumer of virtcontainers tries to start/stop a container,
or stop a pod, and for some reasons, this fails, virtcontainers always
tries to delete everything related to the container or the pod before
it returns the error.
The caller of the runtime is the one responsible for cleaning things
up if something goes wrong, that's why this cleanup call is never
needed.
A real example of that is the case of cc-runtime and CRI-O, where this
cleanup prevented CRI-O from retrieving proper state of the container
after the failure, leading to the inability to stop and remove the
container and the VM afterwards.

This commit modifies version.yaml to now point to the qemu
2.11 stable version.
It modifies the default QEMU_CMD to be qemu-system-x86_64
instead of qemu-lite-system-x86_64.
And modifies virtcontainers unit tests to now point to the
correct QEMU_CMD.

The kata_agent.go code breaks after the first /dev/shm. But in case
several are defined, the agent will crash since other /dev/shm will
be wrongly configured in the OCI spec mounts.

Instead of ignoring containers based on their path, this commit
relies on the type of mount being "bind" to choose if this mount
should be ignored or not.
For instance, we have some use cases where k8s expects the path
"/dev/container-log" to be bind mounted inside the container, but
the code ignores it because it has the prefix "/dev" which is a
system prefix mount.

Don't use a copy of the go test script, use the central version for

Add a YAML format database that is the equivalent of the Clear
Containers `versions.txt` file [1].
The file defines the versions of important non-golang dependencies used
by this and other Kata repositories particularly for testing and packaging.
Defining all version details centrally in this file avoids duplication
and "bit-rot" when versions need to be changed.

Add `initrd=[path]` option to configuration.toml and use it to set
the HypervisorConfig.InitrdPath option.
The default value of hypervisor image option is removed since we want
to allow it to be unset. For the same reason, there is no default value
for hypervisor initrd option either.

This patch introduces a bash library (scripts/lib.sh) that concentrates
common functions. This also enhances future additions of other OSes, making
it more simple. Also, new variables were introduced in each distro config.sh
in order to parameterise the creation of package manager config (dnf/yum, in this case).
A fix to the resulting rootfs directory name (include OS name) is also fixed in this
patch.
