For a privilege pods with PrivilegedWithoutHostDevices set to true
host device specified in the config are not provided (whereas it is done for
non privilege pods or privilege pods with PrivilegedWithoutHostDevices set
to false as all devices are included).
Add them in this case.
Fixes: 3353ab76d9 ("Add flag to overload default privileged host device behaviour")

Throughout container lifecycle, pulling image is one of the time-consuming
steps. Recently, containerd community started to tackle this issue with
stargz-based remote snapshots, as a non-core
subproject(https://github.com/containerd/stargz-snapshotter).
This snapshotter is implemented as a standard proxy plugin but it requires the
client to pass some additional information (image ref and layer digest) for each
pull operation to query layer contents on the registry. Stargz snapshotter
project provides an image handler to do this and stargz snapshot users need to
pass this handler to containerd client.
This commit enables to use stargz-based remote snapshots through CRI by passing
the handler to containerd client on pull operation.

Along with type(Sandbox or Container) and Sandbox name annotations
provide support for additional annotation:
- Container name
This will help us perform per container operation by comparing it
with pass through annotations (eg. pod metadata annotations from K8s)

With go RWMutex design, no goroutine should expect to be able to
acquire a read lock until the read lock has been released, if one
goroutine call lock.
The original design is to reload cni network config on every single
Status CRI gRPC call. If one RunPodSandbox request holds read lock
to allocate IP for too long, all other RunPodSandbox/StopPodSandbox
requests will wait for the RunPodSandbox request to release read lock.
And the Status CRI call will fail and kubelet becomes NOTReady.
Reload cni network config at every single Status CRI call is not
necessary and also brings NOTReady situation. To lower the possibility
of NOTReady, CRI will reload cni network config if there is any valid fs
change events from the cni network config dir.

`systemctl is-enabled` is not a reliable indicator that the docker service should be started. Docker service may be running even if marked as disabled.

The resize chan is never closed when doing exec/attach now. What's more,
`resize` is a recieved only chan so it can not be closed. Use ctx to
exit the goroutine in `handleResizing` properly.
