1. Core Kubelet changes to implement In-place Pod Vertical Scaling.
2. E2E tests for In-place Pod Vertical Scaling.
3. Refactor kubelet code and add missing tests (Derek's kubelet review)
4. Add a new hash over container fields without Resources field to allow feature gate toggling without restarting containers not using the feature.
5. Fix corner-case where resize A->B->A gets ignored
6. Add cgroup v2 support to pod resize E2E test.

The changes (mostly in pkg/kubelet/cm) are there to adopt changed
runc 1.1 API, and simplify things a bit. In particular:
1. simplify cgroup manager instantiation, using a new, easier way of
libcontainers/cgroups/manager.New;
2. replace libcontainerAdapter with a boolean variable (all it did
was passing on whether systemd manager should be used);
3. trivial change due to removed cgroupfs.HugePageSizes and added
cgroups.HugePageSizes();
4. do not calculate cgroup paths in update / destroy, since libcontainer
cgroup managers now calculate the paths upon creation (previously,
they were doing that only in Apply, so using e.g. Set or Destroy right
after creation was impossible without specifying paths).
We currently still calculate cgroup paths in Exists -- this is to be
addressed separately.

The remote runtime implementation now supports the `verbose` fields,
which are required for consumers like cri-tools to enable multi CRI
version support.

This patch makes the CRI `v1` API the new project-wide default version.
To allow backwards compatibility, a fallback to `v1alpha2` has been added
as well. This fallback can either used by automatically determined by
the kubelet.

Seperate the CPU/Memory req/limit -> linux resource conversion into its
own function for better reuse.
Elsewhere in kuberuntime pkg, we will want to leverage this
requests/limits to Linux Resource type conversion.

We've changed the Ephemeral Containers API, and container type will no
longer be required. Since this is the only feature using it, remove it.
This reverts commit ba6f31a6c6.
Users must not be allowed to step outside the volume with subPath.
Therefore the final subPath directory must be "locked" somehow
and checked if it's inside volume.
On Windows, we lock the directories. On Linux, we bind-mount the final
subPath into /var/lib/kubelet/pods/<uid>/volume-subpaths/<container name>/<subPathName>,
it can't be changed to symlink user once it's bind-mounted.
