Implement function to check if the system has support for vsocks.
This function looks for vsock and vhost-vsock devices returning
true if those exist, otherwise false.

So that if there is any remaining state, we do not let it interfere
with the new one. This should fix the occasional vm factory hang.

This commit imports a big logic change:
* host device to be attached or appended now is sandbox level resources,
one device should bind to sandbox/hypervisor first, then container could
reference it via device's unique ID.
* attach or detach device should go through the device manager interface
instead of the device interface.
* allocate device ID in global device mapper to guarantee every device
has a uniq device ID and there won't be any ID collision.
With this change, there will some changes on data format on disk for sandbox
and container, these changes also make a breakage of backward compatibility.
New persist data format:
* every sandbox will get a new "devices.json" file under "/run/vc/sbs/<sid>/"
which saves detailed device information, this also conforms to the concept that
device should be sandbox level resource.
* every container uses a "devices.json" file but with new data format:
```
[
{
"ID": "b80d4736e70a471f",
"ContainerPath": "/dev/zero"
},
{
"ID": "6765a06e0aa0897d",
"ContainerPath": "/dev/null"
}
]
```
`ID` should reference to a device in a sandbox, `ContainerPath` indicates device
path inside a container.

Instead of using drivers.XXXDevice directly, we should use exported
struct from device structure. package drivers should be internal struct
and other package should avoid read it's struct content directly.

The interface "VhostUserDevice" has duplicate functions and fields with
Device, so we can merge them into one interface and manage them with one
group of interfaces.

Previously the devices are created with device manager and laterly
attached to hypervisor with "device.Attach()", this could work, but
there's no way to remember the reference count for every device, which
means if we plug one device to hypervisor twice, it's truly inserted
twice, but actually we only need to insert once but use it in many
places.
Use device manager as a consolidated entrypoint of device management can
give us a way to handle many "references" to single device, because it
can save all devices and remember it's use count.

Ensure the entire codebase uses `"sandbox"` and `"container"` log
fields for the sandboxID and containerID respectively.
Simplify code where fields can be dropped.

Refine the changes made on #468 by adding the containerID log field as
soon as possible (before *any* virtcontainers calls). This requires
that `setExternalLoggers()` be called more times, but it's essential to
ensure the correct log fields are available as early as possible.
Partially fixes#519.

Now that the `SetLogger()` functions accept a `logrus.Entry`, they can
access the fields that have already been set for the logger and
re-apply them if `SetLogger()` is called multiple times.
This fixes a bug whereby the logger functions -- which are necessarily
called multiple times [1] -- previously ended up applying any new fields
the specified logger contained, but erroneously removing any additional
fields added since `SetLogger()` was last called.
Partially fixes#519.

This PR got merged while it had some issues with some shim processes
being left behind after k8s testing. And because those issues were
real issues introduced by this PR (not some random failures), now
the master branch is broken and new pull requests cannot get the
CI passing. That's the reason why this commit revert the changes
introduced by this PR so that we can fix the master branch.
