When a container is just created, exited state the container will not have stats. A common case for this in k8s is the init containers for a pod. The will be present in the listed containers but will not have a running task and there for no stats.

The 10-containerd-net.conflist file generated from the conf_template
should be written atomically so that partial writes are not visible to
CNI plugins. Use the new consistentfile package to ensure this on
Unix-like platforms such as Linux, FreeBSD, and Darwin.
Fixes https://github.com/containerd/containerd/issues/8607

The initial PR had a check for nil metrics but after some refactoring in the PR the test case that was suppose cover HPC was missing a scenario where the metric was not nil but didn't contain any metrics. This fixes that case and adds a testcase to cover it.

Windows systems are capable of running both Windows Containers and Linux
containers. For windows containers we need to sanitize the volume path
and skip non-C volumes from the copy existing contents code path. Linux
containers running on Windows and Linux must not have the path sanitized
in any way.
Supplying the targetOS of the container allows us to proprely decide
when to activate that code path.

If containerd does not see a container but criservice's
container store does, then we should try to recover from
this error state by removing the container from criservice's
container store as well.

Using array to build sub-tests is to avoid random pick. The shuffle
thing should be handled by go-test framework. And we should capture
range var before runing sub-test.

In the CRI server initialization a syncgroup is setup that adds to the
counter for every cni config found/registered. This functions on platforms
where CNI is supported/theres an assumption that there will always be
the loopback config. However, on platforms like Darwin where there's generally
nothing registered the Wait() on the syncgroup returns immediately and the
channel used to return any Network config sync errors is closed. This channel
is one of three that's used to monitor if we should Close the CRI service in
containerd, so it's not great if this happens.

options got from the podspec.

1. it's easy to check wrong input if using drain_exec_sync_io_timeout in error
2. avoid to use full error message, as part of error generated by go
stdlib would be changed in the future
3. delete the extra empty line
