Julio Montes 8ddd892072 libcontainer: add method to get cgroup config from cgroup Manager
`configs.Cgroup` contains the configuration used to create cgroups. This
configuration must be saved to disk, since it's required to restore the
cgroup manager that was used to create the cgroups.
Add method to get cgroup configuration from cgroup Manager to allow API users
save it to disk and restore a cgroup manager later.

fixes #2176

Akihiro Suda 88e8350de2 cgroup2: split fs2 from fs
split fs2 package from fs, as mixing up fs and fs2 is very likely to result in
unmaintainable code.

Inspired by containerd/cgroups#109

Fix #2157

James Peach 13919f5dfd Remove the static_build build tag.
The `static_build` build tag was introduced in e9944d0f
to remove build warnings related to systemd cgroup driver
dependencies. Since then, those dependencies have changed and
building the systemd cgroup driver no longer imports dlopen.

After this change, runc builds will always include the systemd
cgroup driver.

This fixes #2008.

Akihiro Suda dbd771e475 cgroup2: implement `runc ps`
Implemented `runc ps` for cgroup v2 , using a newly added method `m.GetUnifiedPath()`.
Unlike the v1  implementation that checks `m.GetPaths()["devices"]`, the v2 implementation does not require the device controller to be available.
