Since we now have "unix://" kind of socket returned by the
SocketAddress() function, there is no more need to build the sandbox
storage path dynamically to keep OS compatibility.

(cherry picked from commit bfb556d56a)
When the container engine is different than containerd or CRI-O we
lack proper detection of kata workloads and consider all the pods as
kata ones.
Instead of querying the container engine for the lower level runtime
used in each pod, check if a directory matching the pod exists in
the virtualcontainers sandboxes storage path.
This provides a container engine independent way to check for kata pods.

(cherry picked from commit afad910d0e)
The storage path we use to collect the sandbox files is defined in the
virtcontainers/persist/fs package.
We create the runtime socket in that storage path, by hardcoding the
full path in the SocketAddress() function in the runtime package.
This commit splits the hardcoded path by the socket address path so that
the runtime package will be able to provide the storage path to all the
components that may need it.

(cherry picked from commit e38686f74d)
In order to retrieve the list of sandboxes, we poll the container engine
every 15 seconds via the CRI. Once we have the list we have to inspect
each pod to find out the kata ones.
This commit extend the sandbox cache to keep track of all the pods,
marking the kata ones, so that during the next polling only the new
sandboxes should be inspected to figure out which ones are using the
kata runtime.

Backport from commit 72e3538e36
Signed-off-by: Christophe de Dinechin <dinechin@redhat.com>
A discussion on the Linux kernel mailing list [1] exposed that virtiofsd makes a
core assumption that the file systems being shared are not accessible by any
non-privileged user. We currently create the `shared` directory in the sandbox
with the default `0750` permissions, which gives read and directory traversal
access to the group. There is no real good reason for a non-root user to access
the shared directory, and this is potentially dangerous.

In getThreadIDs(), the cpuID variable is derived from a string that
already contains a whitespace. As a result, strings.SplitAfter returns
the cpuID with a leading space. This makes any go variant of string to int
fail (strconv.ParseInt() in our case). This patch makes sure that the
leading space character is removed so the string passed to
strconv.ParseInt() is "CPUID" and not " CPUID".
This has been caused by a change in the naming scheme of vcpu threads
for Firecracker after v0.19.1.

Change logger in Trace call in newContainer from sandbox.Logger() to
nil. Passing nil will cause an error to be logged by kataTraceLogger
instead of the sandbox logger, which will avoid having the log message
report it as part of the sandbox subsystem when it is part of the
container subsystem.
The kataTraceLogger will not log it as related to the container
subsystem, but since the container logger has not been created at this
point, and we already use the kataTraceLogger in other instances where a
subsystem's logger has not been created yet, this PR makes the call
consistent with other code.

We keep the container engine info in the sandbox cache map, as the value
associated to the pod id (the key). Since we used that in
getMonitorAddress() only (which is gone) we can avoid storing that
information. Let's drop it.
Keep the map structure and the [put,delete]IfExists functions as we may
want to move to an event based cache update process sooner or later, and
we will need those.

Bin Liu (bin <bin@hyper.sh>) worked on a kata-monitor version able
to talk to any container engine leveraging the standard CRI[1].
Here, the original work of Bin Lui has been adapted on the current
kata-monitor to make it container engine independent.

Kata uses the 'kernel_irqchip' machine option to qemu. By default it
uses it in what qemu calls the "short-form boolean" with no parameter.
That style was deprecated by qemu between 5.2 and 6.0 (commit
ccd3b3b8112b) and effectively removed entirely between 6.0 and 6.1
(commit d8fb7d0969d5).
Update ourselves for newer qemus by using an explicit
"kernel_irqchip=on".
