Outputs produces unnecessarily multidimensional objects

[cosmindev]

Output variables in the format of unnecessarily multidimensional arrays which are hard to query by other tf code using this module:

• output code example:
  output "public_ip" { description = "Public IPs of created instances. " value = ["${module.instance.public_ip}"] }
• generated output:
  public_ip = [ [ "132.145.XX.YY", "132.145.XX.YY", ], ]
• Example usecase: remote exec connection blocks

provisioner "file" {   connection {     user        = "opc"     agent       = false     private_key = "${chomp(file(var.ssh_private_key_path))}"     timeout     = "10m"     host        = "${module.instance.public_ip[count.index]}"   }     source      = "apache_install.sh"   destination = "/tmp/apache_install.sh" }

the above syntax for getting the host public IP it will not work with multidimensional arrays and it will require unnecessarily complex element()/lookup() functions usage.
