Populate CRI filesystem info error 
Usually we just log the error but since it's used by the GC we now
populate it up the call stack.

Make kubelet label types public 
We use the label definitions in CRI-O, means we now make them public to
stop vendoring/copying this part of Kubernetes.

kubelet: Move Linux stats to a Linux specific file 
This commit moves the Linux stats from CRI to a linux specific
file and adds unimplemented methods for platform other than
Linux and Windows.

Do not error log CRI stats for not cached partitions 
We do not have any cached partitions available on Kubelet start with an
empty container storage in CRI-O. This means that the error log message
is not actually an error and more an information.

This means we now pre-filter those cases and do not `klog.ErrorS` any
more. This helps to avoid log spamming in huge clusters.

b9bf3e5c49 Replaces path.Operation with filepath.Operation (kubelet) 
The path module has a few different functions:
Clean, Split, Join, Ext, Dir, Base, IsAbs. These functions do not
take into account the OS-specific path separator, meaning that they
won't behave as intended on Windows.

For example, Dir is supposed to return all but the last element of the
path. For the path "C:\some\dir\somewhere", it is supposed to return
"C:\some\dir\", however, it returns ".".

Instead of these functions, the ones in filepath should be used instead.

Make CRI v1 the default and allow a fallback to v1alpha2 
This patch makes the CRI `v1` API the new project-wide default version.
To allow backwards compatibility, a fallback to `v1alpha2` has been added
as well. This fallback can either used by automatically determined by
the kubelet.
