tf localfiles support in brokerpak

[dmachard]

Hi,

I submit you this pull request to support terraform localfiles in the brokerpak regarding the issue #114 .
The schema of the YAML services has been updated with a new action object "localfiles-refs" as part of a provision or bind action.

provision:
  template_ref: terraform/myservice/main.tf
  localfile_refs:
    - terraform/myservice/foo.bar
    - terraform/myservice/listips.tmpl
    - terraform/myservice/libcreate.py

After that local files can be used in terraform files like below

locals {
  listips = templatefile("${path.module}/listips.tmpl", { port = 8080, ip_addrs = ["10.0.0.1", "10.0.0.2"] })
}

data "local_file" "foo" {
    filename = "${path.module}/foo.bar"
}

resource "null_resource" "api" {
    provisioner "local-exec" {
        command = "python3 ${path.module}/libcreate.py"
    }
}

Closing this pull request as discussion in #114 is pointing us in a different direction.
Thanks @dmachard for your contribution. Hope to see more of this.
