Reason for Change:
Today we use dropgz as an initcontainer to bring the cilium conflist to clusters. This PR allows for CNS to write the cilium conflist instead. Dropgz will still be required to install azure-ipam. This feature already exists for the overlay scenario, and it keeps nodes in NotReady state until the network is ready. Now, CNS can write the cilium conflist if we set in the cnsconfig: EnableCNIConflistGeneration as true, specify the conflist scenario to cilium, and set the conflist filepath.
Issue Fixed:
Requirements:
Notes:
Changes were validated in byocni overlay-cilium and byocni pod subnet cilium clusters. The azure-cns deployment was modified so that dropgz only installs azure-ipam, and CNS writes the cilium conflist to etc/cni/net.d.
