Public bug reported:

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.
