clusterctl dhcp capture

clusterctl dhcp capture
Capture DHCP traffic on the server
Synopsis
Run a bounded packet capture of the DHCP exchange on the server, which is what to do when a node asks for an address and nothing answers.
The capture stops on its own after the given time, so it cannot be left running by accident.
