Two endpoints cannot have the same ID

[ivanocerrato]

The following graph is wrong because the two endpoints have both ID 1. However the unorch does not recognize any error.

"end-points": [
  {
    "interface": {
      "if-name": "eth1"
    },
    "type": "interface",
    "id": "1",
    "name": "OVS-north external port"
  },
  {
    "interface": {
      "if-name": "eth2"
    },
    "type": "interface",
    "id": "1",
    "name": "OVS-south external port"
  }
],

Fixed. I'm going to fix the same issue related to the VNFs IDs.

Fixed both the issues (on endpoints ID and on VNFs ID).
