07878325c3 cgroup2: Add Kill method 
Fixes: #98

Add a Kill method for cgroups v2. This uses the new functionality in
kernels 5.14+ where writing to a cgroup.kill file will send a SIGKILL
to every process running in the cgroup. This would be useful for
kata to avoid freezing+manually sending SIGKILL+thawing process it
does currently to emulate runc's behavior.

0c908cddf8 memory: set_kmem_limit: ignore Unsupported error 
Setting (writing into) `memory.kmem.limit_in_bytes` is not supported in
Linux kernel >= 5.16 (see kernel commit 58056f77502: "memcg, kmem:
further deprecate kmem.limit_in_bytes"):
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=58056f77502

If the write call in `set_kmem_limit()` returns EOPNOTSUPP, log a
warning message but ignore the error (do nothing).

Add a unit-test for `set_kmem_limit` in cgroups v1.

Fix #81
