Title:
  cloud-net fails when DHCP slow

Status in cloud-init package in Ubuntu:
  Incomplete
Status in subiquity package in Ubuntu:
  Invalid

Bug description:
  During a cloud-init autoinstall with Ubunutu Focal Server 20.04, the
  attempts to retrieve the meta-data file fail immediately with no
  timeout as indicated in the cloud-init.log.  According to the system
  logs, the network does not receive an IP address until after the
  attempt to retrieve the meta-data file.  The DHCP in the facility is
  known to be a little slow.

  It is possible to retrieve the file by switching to a second virtual
  terminal and downloading it with wget (after the failure of the cloud-
  init).  It appears that the url_helper.py function reporting the
  failure to retrieve the files does not wait for any timeout period
  when the network is not yet present.

  Possible solution?  Adding a check with a timeout of a few seconds for
  the network being available before moving to download the meta-data
  and user-data files.
