Iteration zero should not create dev test and staging by default

Should terraform destroy delete user namespaces like dev,staging,test?

When running `terraform destroy` it deletes `tools` namespace, but also the other namespaces created with terraform like dev,staging,test.

When running `terraform destroy` I think it should delete tools, and not user workloads namespaces like dev,staging,test
Deleting these can cause grief or worst deleting workloads are being used.

Maybe it can be a seperate helper script to delete the example workload namespaces created by the user.
