KWQ001 - CNI Web Quest

Kubernetes has adapted Container Network Interface(CNI) as a standard to provide networking between pods running across hosts and to assign those with IP addresses. The purpose of this Web Quest is to compare the CNI plugins available, and make recommendations based on the merit that you find in those.
