Events cli display container events such as cpu,
memory, and IO usage statistics.
By now OOM notifications and intel RDT are not fully supproted.

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.

Update command is used to update container's resources at run time.
All constraints are applied inside the VM to each container cgroup.
By now only CPU constraints are fully supported, vCPU are hot added
or removed depending of the new constraint.

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`.

It disconnects the agent connection and removes the sandbox
from global sandbox list.
A new option `LongLiveConn` is also added to kata
agent's configuration. When set, the API caller is expected
to call sandbox.Release() to drop the agent connection explicitly.
`proxyBuiltIn` is moved out of agent state because we can always
retrieve it from sandbox config instead.

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.

Because of the bad design of the cc_proxy_mock go routine, we were
leaving an infinite loop running into this go routine behind. This
was consuming a lot of resources and it was obviously slowing down
the tests being run in parallel. That's one of the reason we were
hitting the 10 seconds timeout when running go tests.

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.

in order to make log-parser happy, mockcontainer must return
always a valid process with a fake PID, since log-parser checks
that PID value in the logs and it must be different to zero
