CRI: add Message in ContainerStatus
Kubernetes expects a brief CamelCase string as "Reason" and a human-readable
string as "Message" in the conatiner status. It is difficult for kubelet to
derive the other one if the runtime only provides one of the two fields.
Augment the API by adding the "Message" field.

Augment the API by adding the "Message" field.
This is a temporary hack to bypass CRI when getting container logs or
running exec in a container. This is necessary to unblock testing and adding
other features in the integration.
This allows runtimes in different packages (dockertools, rkt, kuberuntime) to
share the same logic. Before this change, only dockertools support this
feature. Now all three packages support image pull throttling.

Instruct PLEG to detect pod sandbox state changes
This PR adds a Sandboxes list in `kubecontainer.Pod`, so that PLEG can check
sandbox changes using `GetPods()` . The sandboxes are treated as regular
containers (type `kubecontainer.Container`) for now to avoid additional
changes in PLEG.

Kubelet: implement GetPodStatus for new runtime API
Implement `GetPodStatus()` for new runtime API. Part of #28789 .
CC @yujuhong @Random-Liu @dchen1107
PLEG will treat them as if they are regular containers and detect changes the
same manner. Note that this makes an assumption that container IDs will not
collide with the podsandbox IDs.

Kubelet: implement GetNetNS for new runtime api
Kubelet: implement GetNetNS for new runtime api.
CC @yujuhong @thockin @kubernetes/sig-node @kubernetes/sig-rktnetes
MTU selection is difficult, and if there is a transport such as IPSEC in
use may be impossible. So we allow specification of the MTU with the
network-plugin-mtu flag, and we pass this down into the network
provider.
Currently implemented by kubenet.
New flag --container-runtime-endpoint (overrides --container-runtime)
is introduced to kubelet which identifies the unix socket file of
the remote runtime service. And new flag --image-service-endpoint is
introduced to kubelet which identifies the unix socket file of the
image service.
