* The DHCP driver used to use device_delegate, but that has changed to device_manager. referencing device_delegate caused the cleanup of the dhcp agent namespaces to fail. This fixes the issue by using the correct member name, device_manager Change-Id: Iab8ea0549383335ff66f3f13df1953d206eeb28f Closes-Bug: #1245408
