48ca6e53e6 memory manager: provide and use the checkpoint manager 
The checkpoint manager provides a way to save the memory manager
`MemoryTable` both under the memory and under the state file.

Saving the `MemoryTable` under the state file can be useful when kubelet
restarted and you want to restore memory allocations for running containers.
Also, it provides a way to monitor memory allocations done by the memory manager,
and in the future, the state file content can be exposed under the pod metrics.

de4602995b Windows: Fixes /etc/hosts file mounting support for containerd 
If Containerd is used on Windows, then we can also mount individual
files into containers (e.g.: /etc/hosts), which was not possible with Docker.

Checks if the container runtime is containerd, and if it is, then also
mount /etc/hosts file (to C:\Windows\System32\drivers\etc\hosts).

de60340e51 Improve the getCgroupSubsystemsV1() which uses random record per subsystem 
returned by libcontainercgroups.GetCgroupMounts().

Example array from GetCgroupMounts():
```
[
        {
                Mountpoint: "/sys/fs/cgroup/systemd",
                Root: "/",
                Subsystems: []string len: 1, cap: 1, ["systemd"],},
        {
                Mountpoint: "/sys/fs/cgroup/cpu,cpuacct",
                Root: "/",
                Subsystems: []string len: 2, cap: 2, ["cpu","cpuacct"],},
        {
                Mountpoint: "/sys/fs/cgroup/systemd/some/path",
                Root: "/some/path",
                Subsystems: []string len: 1, cap: 1, ["systemd"],},
]
```
becames a map:
```
[
        "memory": "/sys/fs/cgroup/memory/kubepods",
        "systemd": "/sys/fs/cgroup/systemd/some/path",
]
```
which seems to be wrong.

Using shortest path of mountpoint per subsystem would be more reliable.

38dc7509f8 cpu manager: specify the container CPU set during the creation 
We can set the container cpuset.cpus diring the creation and it
will not need to call to update resources after the container creation.

Additional side effect of the change, that the runc process that responsible
to create the container will run with the same CPU affinity because the
runc runs on the cpuset provided in the config.json arg.

It will allow to prevent undesirable interupts on isolated CPUs.
