54b24dad4d devices: add vhost-user storage configuration
Two parameters are used to set in toml file:

1. Set "enable_vhost_user_store = true" to indicate
that vhost-user storage device feature is enabled.

2. Set "vhost_user_store_path = <Vhost-User-Dir>".
vhost-user socket files will be under
"<Vhost-User-Dir>/block/sockets/"; and device node
for vhost-user device will be under
"<Vhost-User-Dir>/block/devices/"
The default value of "vhost_user_store_path" is
"/var/run/kata-containers/vhost-user/".

01a12b003b qemu: Add virtio-mem support
This commit adds qemu virtio-mem support.
Then qemu can use virtio-mem support memory resize.

To enable this function, need the Linux and the qemu that support
virtio-mem.
Use command "echo 1 > /proc/sys/vm/overcommit_memory" to enable memory
overcommitment of the Linux kernel.  Because qemu virtio-mem device need
to allocate a lot of memory.
Set "enable_virtio_mem" of kata configuration to true.

78ea50c36c virtcontainers: Jailer: Add jailer support for firecracker
Firecracker provides a jailer to constrain the VMM. Use this
jailer to launch the firecracker VMM instead of launching it
directly from the kata-runtime.

The jailer will ensure that the firecracker VMM will run
in its own network and mount namespace. All assets required
by the VMM have to be present within these namespaces.
The assets need to be copied or bind mounted into the chroot
location setup by jailer in order for firecracker to access
these resouces. This includes files, device nodes and all
other assets.

Jailer automatically sets up the jail to have access to
kvm and vhost-vsock.

If a jailer is not available (i.e. not setup in the toml)
for a given hypervisor the runtime will act as the jailer.

Also enhance the hypervisor interface and unit tests to
include the network namespace. This allows the hypervisor
to choose how and where to lauch the VMM process, vs
virtcontainers directly launching the VMM process.

6107694930 runtime: rename pod to sandbox
As agreed in [the kata containers API
design](https://github.com/kata-containers/documentation/blob/master/design/kata-api-design.md),
we need to rename pod notion to sandbox. The patch is a bit big but the
actual change is done through the script:
```
sed -i -e 's/pod/sandbox/g' -e 's/Pod/Sandbox/g' -e 's/POD/SB/g'
```

The only expections are `pod_sandbox` and `pod_container` annotations,
since we already pushed them to cri shims, we have to use them unchanged.
