Azure: Missing HCL tests

[xescugc]

For Azure the testdata/azure.tf was added but no test using it.

I tried to add the test but the current implementation does not work, some things I've found:

• https://github.com/cycloidio/inframap/blob/master/provider/azurerm/azurerm.go#L72 will never work on HCL as the cfg["id"] will never exists, what has to be done is (IIRC):

func getRsIDByName(cfgs map[string]map[string]interface{}, name interface{}) (string, bool) {
    sname := name.(string)
	for _, cfg := range cfgs {
		rsName := cfg["name"]
		if rsName == name {
			pvid, ok := cfg["id"].(string)
			return pvid, ok
		} else if can, ok = cfg[provider.HCLCanonicalKey]; ok && fmt.Sprintf("${%s.name}",can) == sname {
            return sname, true
        }
	}
	return "", false
}

And also the main issue is that on the HCL the graph build before doing any operation is:

strict digraph G {                                                                                                                                                                                                  
        "azurerm_virtual_network_peering.example-1"->"azurerm_virtual_network.myterraformnetwork";                                                                                                                  
        "azurerm_virtual_network_peering.example-1"->"azurerm_virtual_network.myterraformnetwork2";                                                                                                                 
        "azurerm_linux_virtual_machine.myterraformvm" [ shape=ellipse ];                                                                                                                                            
        "azurerm_linux_virtual_machine.myterraformvm2" [ shape=ellipse ];                                                                                                                                           
        "azurerm_virtual_network.myterraformnetwork" [ shape=ellipse ];                                                                                                                                             
        "azurerm_virtual_network.myterraformnetwork2" [ shape=ellipse ];                                                                                                                                            
        "azurerm_virtual_network_peering.example-1" [ shape=rectangle ];                                                                                                                                            
                                                                                                                                                                                                                    
}

Which means that the azurerm_linux_virtual_machine are not connected to anything and will be removed on the first operation. They are not connected to anything as the "only" allowed connection is azurerm_virtual_network_peering and they do not know it. They know of azurerm_resource_group and azurerm_network_interface and those are not valid Nodes/Edges so are discarted.

The solution should be to add those resources as edges and the attributes needed on the Provider and fix the ResourceInOutNodes to know how to read those Edges.
