  ActivationPolicy=down causes delay at boot

Bug description:
  [impact]

  The ActivationPolicy= parameter was backported in bug 1664844, but
  when this is set to down (or always-down or manual) without also
  specifying RequiredForOnline=no, then there is a hang at boot waiting
  for the network to finish coming online.

  [test case]

  With the latest systemd, which includes support for ActivationPolicy=,
  configure an interface with ActivationPolicy=down and reboot. The boot
  will be delayed waiting for that interface.

  [regression potential]

  any regression would likely cause the system to encounter delay at
  boot, or to boot before configured interface(s) are fully online at
  boot, or to fail to correctly/fully configure interface(s).

  [scope]

  this is needed for all releases

  this is proposed upstream in:
  https://github.com/systemd/systemd/pull/19883

  [other info]

  this is only needed for convenience, as any configuration using
  ActivationPolicy=down can also easily add RequiredForOnline=no
