If the QEMU VMM fails to launch, we currently fail to kill virtiofsd,
resulting in leftover processes running on the host. Let's make sure we
kill these, and explicitly cleanup the virtiofs socket on the
filesystem.
Ideally we'll migrate QEMU to utilize the same virtiofsd interface that
CLH uses, but let's fix this bug as a first step.

In commit 966bd57 for PR #902, the makefile was changed to automate
the replacement of user variables. However, one variable was treated
specially in the original `sed` replacements, namely `RUNTIME_NAME`
which was replaced by `$(TARGET)`.
This commit adds the `RUNTIME_NAME` variable to the makefile in order
to ensure that the replacement works correctly.

Users can specify extra arguments for virtiofsd in a pod spec using the
io.katacontainers.config.hypervisor.virtio_fs_extra_args annontation.
However, this annotation was ignored so far by the runtime. This commit
fixes the issue by processing the annotation value (if present) and
translating it to the corresponding hypervisor configuration item.

There's no reason to ship qemu & qemu-virtiofs when the former already
includes vitiofs support (and that's the default for 2.x deployments).
In case we will enable experimental qemu DAX support, we should add a

A wrong path was being used for container directory when
virtiofs is utilized. This resulted in a warning message in
logs when a container is killed, or completes:
level=warning msg="Could not remove container share dir"
Without proper removal, they'd later be cleaned up when the shared
path is removed as part of stopping the sandbox.

Right now we rely heavily on mount propagation to share host
files/directories to the guest. However, because virtiofsd
pivots and moves itself to a separate mount namespace, the remount
mount is not present in virtiofsd's mount. And it causes guest to be
able to write to the host RO volume.
To fix it, create a private RO mount and then move it to the host mounts
dir so that it will be present readonly in the host-guest shared dir.
Signed-off-by: Peng Tao <bergwolf@hyper.sh>
bindmount remount events are not propagated through mount subtrees,
so we have to remount the shared dir mountpoint directly.
E.g.,
```
mkdir -p source dest foo source/foo
mount -o bind --make-shared source dest
mount -o bind foo source/foo
echo bind mount rw
mount | grep foo
echo remount ro
mount -o remount,bind,ro source/foo
mount | grep foo
```
would result in:
```
bind mount rw
/dev/xvda1 on /home/ubuntu/source/foo type ext4 (rw,relatime,discard,data=ordered)
/dev/xvda1 on /home/ubuntu/dest/foo type ext4 (rw,relatime,discard,data=ordered)
remount ro
/dev/xvda1 on /home/ubuntu/source/foo type ext4 (ro,relatime,discard,data=ordered)
/dev/xvda1 on /home/ubuntu/dest/foo type ext4 (rw,relatime,discard,data=ordered)
```
The reason is that bind mount creats new mount structs and attaches them to different mount subtrees.
However, MS_REMOUNT only looks for existing mount structs to modify and does not try to propagate the
change to mount structs in other subtrees.

Since the kata's hypervisor process is in the network namespace,
which is close to container's process, and some host metrics
such as cadvisor can use this pid to access the network namespace
to get some network metrics. Thus this commit replace the shim's

Today we only clear out the cpuset details when doing an update call on
existing container/pods. This works in the case of Kubernetes, but not
in the case where we are explicitly setting the cpuset details at boot
time. For example, if you are running a single container via docker ala:
docker run --cpuset-cpus 0-3 -it alpine sh
What would happen is the cpuset info would be passed in with the
container spec for create container request to the agent. At that point
in time, there'd only be the defualt number of CPUs available in the
guest (1), so you'd be left with cpusets set to 0. Next, we'd hotplug
the vCPUs, providing 0-4 CPUs in the guest, but the cpuset would never
be updated, leaving the application tied to CPU 0.
Ouch.
Until the day we support cpusets in the guest, let's make sure that we
start off clearing the cpuset fields.

On pod delete, we were looking to read files that we had just deleted. In particular,
stopSandbox for QEMU was called (we cleanup up vmpath), and then QEMU's
save function was called, which immediately checks for the PID file.
Let's only update the persist store for QEMU if QEMU is actually
running. This'll avoid Error messages being displayed when we are
stopping and deleting a sandbox:
```
level=error msg="Could not read qemu pid file"
```
I reviewed CLH, and it looks like it is already taking appropriate
action, so no changes needed.
Ideally we won't spend much time saving state to persist.json unless
there's an actual error during stop/delete/shutdown path, as the persist will
also be removed after the pod is removed. We may want to optimize this,
as currently we are doing a persist store when deleting each container
(after the sandbox is stopped, VM is killed), and when we stop the sandbox.
This'll require more rework... tracked in:
