As github.com/containerd/cgroups doesn't support scope
units which are essential in some cases lets create
the cgroups manually and load it trough the cgroups
api
This is currently done only when there's single sandbox
cgroup (sandbox_cgroup_only=true), otherwise we set it
as static cgroup path as it used to be (until a proper
soultion for overhead cgroup under systemd will be
suggested)

There are `DeviceToDeviceCgroup` and `deviceToDeviceCgroup` two functions,
creating a `specs.LinuxDeviceCgroup` object. We clear the new function `deviceToDeviceCgroup`.

The new API is based on containerd's cgroups package.
With that conversion we can simpligy the virtcontainers sandbox code and
also uniformize our cgroups external API dependency. We now only depend
on containerd/cgroups for everything cgroups related.

Eventually, we will convert the virtcontainers and the whole Kata
runtime code base to only rely on that package.
This will make Kata only depends on the simpler containerd cgroups API.

Pior our bump to runc 1.0.1 the manager's Set() would take a Config as
its parameter. Now it takes the Resources directly.

A significant number of trace calls did not use a parent context that
would create proper span ordering in trace output. Add local context to
functions for use in trace calls to facilitate proper span ordering.
Additionally, change whether trace function returns context in some
functions in virtcontainers and use existing context rather than
background context in bindMount() so that span exists as a child of a
parent span.

CPUSet cgroup allows for pinning the memory associated with a cpuset to
a given numa node. Similar to cpuset.cpus, we should take cpuset.mems
into account for the sandbox-cgroup that Kata creates.
