Add support for disk wiping without GPT formatting

To support a Rook based Ceph cluster, provide an option when wiping
disks to skip adding a partition table. This allows preparing disks on
all hosts during provisioning from the active controller that will be
formatted and run as OSDs when the Rook k8s application is applied.
