Title:
  cloud-init raises an exception when it sees more than 3 nameservers

Status in cloud-init:

Status in cloud-init package in Ubuntu:
  Fix Released
Status in cloud-init source package in Xenial:

Status in cloud-init source package in Yakkety:

Status in cloud-init source package in Zesty:

Bug description:
  When running in an environment that provides more than 3 nameservers,
  cloud-init will raise a ValueError exception:

    Mar 04 18:03:01 localhost.localdomain cloud-init[901]: ValueError:
  Adding '8.8.8.8' would go beyond the '3' maximum name servers

  While that is a legitimate complaint, raising an exception seems like
  the wrong response, because this results in *no* nameserver
  configuration, which can have a substantial operational impact on the
  system.  Cloud-init should probably just log a warning in this case,
  and ignore any nameservers received after the first three.
