QMP doesn't guarantee the order of the array that is returned by
`query-memory-devices` command. So we would better search the whole
array to find out the current max slot, rather than simply use the last
element's slot.

Add new flag "experimental" for supporting underworking features.
Some features are under developing which are not ready for release,
there're also some features which will break compatibility which is not
suitable to be merged into a kata minor release(x version in x.y.z)
For getting these features above merged earlier for more testing, we can
mark them as "experimental" features, and move them to formal features
when they are ready.

Reduce memory footprint ~7% by disabling some systemd services like
systemd-journald and systemd-udevd, those services are just consuming memory
and are not needed. For example kata-agent logs the errors through the proxy.

VMCache is a new function that creates VMs as caches before using it.
It helps speed up new container creation.
The function consists of a server and some clients communicating
through Unix socket. The protocol is gRPC in protocols/cache/cache.proto.
The VMCache server will create some VMs and cache them by factory cache.
It will convert the VM to gRPC format and transport it when gets
requestion from clients.
Factory grpccache is the VMCache client. It will request gRPC format
VM and convert it back to a VM. If VMCache function is enabled,
kata-runtime will request VM from factory grpccache when it creates
a new sandbox.
VMCache has two options.
vm_cache_number specifies the number of caches of VMCache:
unspecified or == 0 --> VMCache is disabled
> 0 --> will be set to the specified number
vm_cache_endpoint specifies the address of the Unix socket.
This commit just includes the core and the client of VMCache.
Currently, VM cache still cannot work with VM templating and vsock.
And just support qemu.

Original guest image was reprensented as block device in qemu-aarch64,
and it will bring up write lock error when running multiple containers.
Thanks to the new expanded IPA_SIZE feature in kernel 4.20 and
Eric Auger's related patch set in qemu(which are still under upstream
review), we could fully support nvdimm on arm64.

This patch fixes the issue where various version of snapshotters,
overlay, block based graphdriver, containerd-shim-v2 overlay, block
based snapshotters mount & create rootfs differently and kata should be
able to handle them all.
The current version of the code always assumes that a folder named
'rootfs' exists within the mount device and that is the path the
container should start at. This patch checks the existing mount point
and if it is the same as the rootFs passed to the container, we no
longer add a suffix to the container's rootfs path.

Makefile:38: arch/aarch64-options.mk: No such file or directory
Makefile:237: *** "ERROR: No hypervisors known for architecture aarch64 (looked for: firecracker qemu)". Stop.
The cause is the machine hardware name of aarch64 is aarch64 but
