Metadata is not refreshed on template resources

[Angus Salkeld]

If you have the following template:

    "custom_lb": {
      "Type": "AWS::EC2::Instance",
      "Properties": {
        "ImageId": {"Ref": "image"},
        "InstanceType": {"Ref": "flavor"},
        "UserData": "foo",
        "SecurityGroups": [ "sg-1" ],
        "Tags": []
      },
      "Metadata": {
        "IPs": {"Fn::GetAtt": ["JobServerGroup", "InstanceList"]}
      }
    },

and you map "AWS::EC2::Instance" to a template resource, the metadata section will not be refreshed when the policy is signalled.

    Make sure template resource's metadata is refreshed

    This copies the code snippet from instance.py, which refreshes
    the metadata when we get a signal on a referenced resource.

    Note: a functional test is coming in a later commit.
