NetworkManager takes a distinctly differnet network management approach and the bulk of the dhcp-all-interfaces code is largely targetted at distribution specific configuration. Some which may or may not override settings, or only partially assert desirable settings. As such, we need to set appropriate configuration, such as the correct client to be used, and timeouts based upon user supplied settings. By default this change sets the client to be dhclient on redhat styled machines, as the packaging default, while it works for ramdisk usage, it does not reset the interface between retries, which can be critical if the infrastucture operator is attempting to configure LACP trunks to the end node.

# shutting down the port between retries which is critical for recovery
