For each time a sandbox structure is created, we ensure s.Release()
is called. Then we can keep the qmp connection as long as Sandbox
pointer is alive.
All VC interfaces are still stateless as s.Release() is called before
each API returns.
OTOH, for VCSandbox APIs, FetchSandbox() must be paired with s.Release,
the same as before.

1. support qemu migration save operation
2. setup vm templating parameters per hypervisor config
3. create vm storage path when it does not exist. This can happen when
an empty guest is created without a sandbox.

A hypervisor implementation does not need to depend on a sandbox
structure. Decouple them in preparation for vm factory.

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.

A Unix domain socket is limited to 107 usable bytes on Linux. However,
not all code creating socket paths was checking for this limits.
Created a new `utils.BuildSocketPath()` function (with tests) to
encapsulate the logic and updated all code creating sockets to use it.
Fixes#268.

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.
