net/keepalived: add notify hotplug-call script handling

Browse source 
During keepalived config generation for the vrrp_instance and vrrp_sync_group
the notify_* sections are automatic added to the runtime keepalived.conf.
This could be used for service which want to react on keepalived notifications.
