OCI runtime spec defines memory.swap as 'limit of memory+Swap usage'
so setting them to equal should disable the swap. Also, this change
should make containerd behaviour same as other runtimes e.g
'cri-dockerd/dockershim' and won't be impacted when user turn on
'NodeSwap' (https://github.com/kubernetes/enhancements/issues/2400) feature.

A majority of the tests in /pkg/cri are testing/validating multiple
things per test (generally spec or options validations). This flow
lends itself well to using *testing.T's Run method to run each thing
as a subtest so `go test` output can actually display which subtest
failed/passed.
Some of the tests in the packages in pkg/cri already did this, but
a bunch simply logged what sub-testcase was currently running without
invoking t.Run.

These unit tests don't check hugetlb. However by setting
TolerateMissingHugetlbController to false, these tests can't
be run on system without hugetlb (e.g. Debian buildd).

limits updated through containerd. The CPU resource limits support
has been added for Windows Server 20H2 and newer, on older versions
hcsshim will raise an Unimplemented error.
