CRI log parser improvements - Modified [`parseCRILog`](https://github.com/kubernetes-incubator/cri-tools/blob/bb2c5293bfa6dd5207e1ce3f2d5a32b09f1cc549/pkg/validate/container.go#L431) to use `strings.SplitN` instead of multiple calls to `strings.Fields`. - Check the resulting array to make sure it has the correct or the expected size and avoid errors when accessing different fields.
