CI was failing on cgroup v2 because mockCgroupManager.GetUnifiedPath()
was returning an error.
Now the function returns the value of mockCgroupManager.unifiedPath,
but the value is currently not used in the tests.

`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.

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.

TestGetContainerStateAfterUpdate creates its state.json file on the current
directory which turns out to be the host runc directory. Thus whenever
the test completes it leaves the state.json file behind thus
a) poluting the local git repository
b) changing the host file system violating the principle of doing
everything in an isolated container environment
This change would create a new temporary (in-container) directory and use it as
linuxContainer.root

state.json should be a reflection of the container's
realtime state, including resource configurations,
so we should update state.json after updating container
resources.

fix#1476
If containerA shares namespace, say ipc namespace, with containerB, then
its ipc namespace path would be the same as containerB and be stored in
`state.json`. Exec into containerA will just read the namespace paths
stored in this file and join these namespaces. So, if containerB has
already been stopped, `docker exec containerA` will fail.
To address this issue, we should always save own namespace paths no
matter if we share namespaces with other containers.

No substantial code change.
Note that some style errors reported by `golint` are not fixed due to possible compatibility issues.
