The "Failed to allocate HTAB of requested size,
try with smaller maxmem" error in ppc64le occurs
when maxmem allocated is very high. This got fixed
in qemu 2.10 and kernel 4.11. Hence put a maxmem
restriction of 32GB per kata-container if qemu
version less than 2.10

This commit checks the size of "/dev/shm" for the sandbox container
which is then used to create the shared memory inside the guest.
kata agent then uses this size to set up a sandbox level ephemeral
storage for shm. The containers then simply bind mount this sandbox level
shm.
With this, we will now be able to support docker --shm-size option
as well have a shared shm within containers in a pod, since they are
supposed to be in the same IPC namespace.

The CPUinfo need to be refined in Arm architecture, because the
vendor and model of CPU may refer to different meaning in Arm architecture.
Besides, relevant contents extracted from /proc/cpuinfo may need to be
normalized for human-readability.

Instead of pausing the sanbox, this patch just pauses the container
allowing the communication with the agent. The communication with the agent
should be still possible even if all containers are paused, because of we don't
know when a new container can be created in the same sandbox.

Pause and resume container functions allow us to just pause/resume a
specific container not all the sanbox, in that way different containers
can be paused or running in the same sanbox.

When a container is updated, those modifications are stored, to
avoid race conditions with other operations, a RW lock should be used.

k8s provides a configuration for sharing PID namespace
among containers. In case of crio and cri plugin, an infra
container is started first. All following containers are
supposed to share the pid namespace of this container.
In case a non-empty pid namespace path is provided for a container,
we check for the above condition while creating a container
and pass this out to the kata agent in the CreatContainer
request as SandboxPidNs flag. We clear out the PID namespaces
in the configuration passed to the kata agent.

add a log field to show which location was used.
Change log level from Debug to Info as this is generally useful
information.
