wake-on-lan: add option to keep existing settings

Browse source 
Add a new 'ignore' option to NMSettingWired.wake-on-lan which disables
management of wake-on-lan by NetworkManager (i.e. the pre-existing
option will not be touched). Also, change the default behavior to be
'ignore' instead of 'disabled'.
