Subject: on-dhcp-event.sh: T2486: modify for new vyos-hostsd syntax

- remove already existing entry check in /etc/hosts as vyos-hostsd will handle it
- vyos-hostsd-client syntax changed
- change tag "DHCP-$client_ip" to "dhcp-server-$client_ip" to make it more
  distinct from dhcp client tag "dhcp-$intf"
