Provider attribute is moved from partition to network-partition

[Rajkumar Rajaratnam]

Hi Devs,

I have now moved provider attribute from partition to network-partition. So
all the partitions defined in a network partition belong the a IaaS
provider. This is the new network partition schema.

{
    "id": "network-partition-2",
    "provider": "ec2",
    "partitions": [
        {
            "id": "network-partition-2-partition-1",
            "property": [
                {
                    "name": "region",
                    "value": "someRegion"
                }
            ]
        },
        {
            "id": "network-partition-2-partition-2",
            "property": [
                {
                    "name": "region",
                    "value": "someRegion"
                }
            ]
        }
    ]
}

Thanks.
