Status in cloud-init:
  Expired

Bug description:
  Reproduction Procedure：
  1、Configuring the dhclient.conf file：
  send host-name = gethostname();

  request subnet-mask, broadcast-address, time-offset, routers,
          domain-name, domain-name-servers, domain-search, host-name,
          dhcp6.name-servers, dhcp6.domain-search,
          netbios-name-servers, netbios-scope, interface-mtu,
          ntp-servers, classless-static-routes;

  supersede domain-name-servers 8.8.8.8;
  supersede domain-search "mydomain.example.com";
  supersede classless-static-routes 0 192.168.0.1;

  timeout 60;
  retry 300;
  script "/sbin/dhclient-script";

  2、bonding nic to bond0
  nmcli con add type bond con-name bond0 ifname bond0 mode active-backup
  nmcli con add type bond-slave ifname enp3s0 master bond0
  nmcli con up bond-slave-enp3s0

  3、running cloud-init init --local
  4、ephemeral IP do not cleanup （enp3s0）
