Subject: support local cdroms

Local cdroms can now be added directly to the domain. See the
following example:

```hcl
resource "libvirt_domain" "test-domain" {
    name = "test"

    disk {
	file = "path/to/file.iso"
    }
}
```

Furthermore, a small Tiny Core Linux (TCL) ISO image has been added to
the testdata. This can be used for testing purposes.
