Let's define agnostic commonkernelRootParams for all hypervisors,
including qemu, firecracker, etc. for now, it has two scenarios,
one for NVDIMM, one for virtio-blk.

A file based memory backend mapped to the host, fot eg: '/dev/shm' will
be used by virtio-fs for performance reasons. This change is a generic
implementation of that for kata. This will be enabled default for
virtio-fs negating the need to enable hugepages in that scenario. This
option can be used without virtio-fs by setting 'file_mem_backend' to
the location in the configuration file. Default value is an empty
string.

After previous commit, found that kata-proxy is not quit
when vmcache server is stopped by ctrl-c.
The cause is current kata-proxy is setsid when it exec. It will
not get the signal ctrl-c.
Call vm.Disconnect() when close vm in cache factory to handle
this issue.

There is an issue that ctrl-c stop vmcache server will stop all
containers that its VM is created by it.
The cause is kata-proxy and vmcache server use same tty, for example:
ps -e | grep kata
3617 pts/5 00:00:00 kata-runtime
3636 pts/5 00:00:00 kata-proxy
Ctrl-c will send signal to both kata-proxy and vmcache server.
Then the containers that its VM is created by this vmcache server will
quit with it.
Set Setsid to true when exec kata-proxy to handle this issue.

We should not let shim or proxy read guest console socket if
agent debug console is set. Otherwise when we connect to it with
socat, it reads nothing since all output is read by the shim.

If kata containers is using vfio and vhost net，the unbinding
of vfio would be hang. In the scenario, vhost net kernel thread
takes a reference to the qemu's mm, and the reference also includes
the mmap regions on the vfio device file. so vhost kernel thread
would be not released when qemu is killed as the vhost file
descriptor still is opened by shim v2 process, and the vfio device
is not released because there's still a reference to the mmap.

Got a defunct kata-proxy after kata quit when VMCache is enabled.
The reason is vmcache server opens kata-proxy but doesn't wait it.
If VMCache is disabled, kata-runtime will quit before kata-proxy.
So it will not meet the issue.
Open a special goroutine do cmd.Wait in kataProxy.start to handle
the isssue.

For the time being cache="none" is recommended, but the other modes can

This change updates the isSystemMount check for mountSharedDirMounts
when setting up shared directory mounts for the container and uses
the source of the mount instead of the destination for the check.
We want to exclude system mounts from the host side as they
shouldn't be mounted into the container.
We do however want to allow system mounts within the
container as denying them can prevent some containers from
running properly.
