Terraform: connection block not validated if not present

[jbardin]

When using a provisioner that requires a connection to the remote host, a missing connection block is not validated at all, causing the provisioner to repeatedly attempt and fail to connect.

resource "null_resource" "vm" {
  provisioner "remote-exec" {
    inline = [
      "echo ok",
    ]
  }
}

Log:

null_resource.vm (remote-exec): Connecting to remote host via SSH...
null_resource.vm (remote-exec):   Host:

The host field is always required, and the configuration should fail during validation.

We have more complaints about this, would it be possible to fix this? Is there something we can do?
