Update resources object

[cesarpomar]

Nomad v1.1.3

"Resources": {
  "CPU": 0,
  "Cores": 1,
  "MemoryMB": 100,
  "MemoryMaxMB": 0,
  "DiskMB": 0,
  "IOPS": 0,
  "Networks": null,
  "Devices": null
},

Java sdk 0.11.3.0

public final class Resources extends ApiObject {
    private Integer cpu;
    private Integer memoryMb;
    private Integer diskMb;
    private List<NetworkResource> networks;
    private List<RequestedDevice> devices;
    private Integer iops;

I need the Cores parameter to limit a docker container.
