Add terraform cloud init example with loop

terraform/example/cloud-init-with-loop.tf

+# Main configuration for our project.
+# This example is quite overkill, this is an example that
+# iterates over a list of vms and reuses the same resource object.
+
+# You don't have to use this file, but I recommend it.
+# Larger example: https://git.sch.bme.hu/kszk/sysadmin/kubernetes/cluster-setup/-/tree/master/terraform
