count is not implemented in data sources

[romachalm]

Hi,

Terraform Version

Terraform v0.7.2

Affected Resource(s)

Related to data sources implementation
error noticed with

• data.template_file
• data.null_data_source

Terraform Configuration Files

data "template_file" "check_connection_to_jboss" {
    count = "2"
    template = "${file("${path.root}/files/consul/check_connection_to_jboss.json.tpl")}"
    vars {
        aps = "${element(azurerm_virtual_machine.aps.*.name, count.index)}"
    }
}

Expected Behavior

I need to generate specific consul check scripts for each created node.
To do that, I have looped on the VMs count and pass them as vars to rendered templates.
It was working fine with terraform 0.6.16. To migrate in 7.2, I have transformed

resource "template_file" "check_connection_to_jboss" {

into

data "template_file" "check_connection_to_jboss" {

Actual Behavior

I got the message

• data.template_file.check_connection_to_jboss config: bundle metadata requires global constraints #1: : invalid or unknown key: count
• data.template_file.check_connection_to_jboss #0: : invalid or unknown key: count

I cannot see in the documentation reference to supported meta-parameters for data sources.
I have found the same limitation with null_data_source.
So, I would assume that this affects any data source.

Steps to Reproduce

terraform plan

I confirm it is solved in 0.7.3.
Thanks for the fix
