Simon Leinen 0ff40cf63c Turn off strict_id mode for Ec2 datasource
Recent changes in the default configuration of cloud-init in Ubuntu
cause warnings when the Ec2 datasource is used on non-Amazon clouds,
see https://bugs.launchpad.net/cloud-init/+bug/1660385

We explicitly select the previous behavior when an Ec2 datasource is
desired.
