introduces Alpha support for a new kubelet-managed pod condition in
the status field of a pod:PodHasNetwork.The kubelet,
for a worker node, will use the PodHasNetwork
condition to accurately surface the initialization state of a pod
from the perspective of pod sandbox creation and network
configuration by a container runtime (typically in coordination
with CNI plugins).The kubelet starts to pull container images and
start individual containers (including init containers) after the
status of the PodHasNetwork condition is set to
True.
