Bug description:
  [impact]

  networkd dhcpv4 client never attempts more than 2 renew and 2 rebind

  [test case]

  configure an interface to use dhcpv4; acquire a dhcpv4 address, then
  stop the dhcpv4 server, and wait for the networkd client to perform
  its renewals and rebinds before expiring the lease

  using a 20 minute lease time as an example (all times are approximate
  due to RFC-mandated random 'fuzz' time of -1 to +1 sec):

  the current behavior would be to sent renew requests at:

  10:00
  13:45

  and then rebind requests at:

  17:30
  18:45

  then the lease would expire at 20:00

  the correct/new behavior should be renew requests at:

  10:00
  13:45
  15:37
  16:37

  and then rebind requests at:

  17:30
  18:45
  19:45

  and then lease expiration at 20:00.

  longer lease times would increase the number of retransmissions.

  [regression potential]

  any regression would likely result in problems receiving and/or
  maintaining a dhcpv4 address

  [scope]

  this is needed in b/f/g/h.

  this was fixed upstream in:
  https://github.com/systemd/systemd/pull/17908

  that was just added, so this is not fixed in any ubuntu release yet.

  technically, this is needed in x as well, however I don't plan to
  backport to x since 1) it reaches ESM soon and 2) the default network
  management tool in x is ifupdown, not systemd-networkd.
