Improve cc_set_passwords.

• If the system doesn't use systemd and the status of the ssh
  service is not 0, then apply the pw_auth config. As distros as
  Alpine could start the ssh service later in the boot sequence.

• Change log level from warning to debug when ssh_pwauth is
  written but the ssh service is not restarted.

Let's move this not uses_systemd conditional first so we can avoid compound conditionals for the uses_systemd exit_code 3 & 4 cases.

[blackboxsw]

It probably makes sense to shuffle this condition up first so we can drop the if uses_systemd and ... in the other conditionals

if not distro.uses_systemd():
    <your new debug log>
elif e.exit_code == 3:
   <existing exit_code 3 behavior>
elif e.exid_code == 4:
   < existing exit_code 4 behavior>
else:
   LOG.warning(Ignoring...)
   return
