in old specs.Spec, Capabilities is [] string, but we don't use CompatOCISpec
for compatibility in kataAgent/createContainer.

Don't fail if a new container with a CPU constraint was added to
a POD and no more vCPUs are available, instead apply the constraint
and let kernel balance the resources.

An empty string for an environment variable simply means that the
variable is unset. Do not error out if the env value is empty.

This is done for decoupling device management part from other parts.
It seperate device.go to several dirs and files:
```
virtcontainers/device
├── api
│ └── interface.go
├── config
│ └── config.go
├── drivers
│ ├── block.go
│ ├── generic.go
│ ├── utils.go
│ ├── vfio.go
│ ├── vhost_user_blk.go
│ ├── vhost_user.go
│ ├── vhost_user_net.go
│ └── vhost_user_scsi.go
└── manager
├── manager.go
└── utils.go
```
* `api` contains interface definition of device management, so upper level caller
should import and use the interface, and lower level should implement the interface.
it's bridge to device drivers and callers.
* `config` contains structed exported data.
* `drivers` contains specific device drivers including block, vfio and vhost user
devices.
* `manager` exposes an external management package with a `DeviceManager`.

When imported, the vc files carried in the 'full style' apache
license text, but the standard for kata is to use SPDX style.
Update the relevant files to SPDX.

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.

If an initrd image is configured in HypervisorConfig or passed in by
annotations, append it to qemu command line arguments.

Some virtcontainers pieces of code are importing virtcontainers
packages. We need to change those paths to point at
kata-containers/runtime/virtcontainers
