Application policy schema is changed!

[Rajkumar Rajaratnam]

Hi Devs,

I have now changed the application policy schema as below. This is the same
schema that Imesh proposed in other thread .

{
    "id": "application-policy-1",
    "algorithm":"one-after-another",
    "networkPartitions":[
        "network-partition-1",
        "network-partition-2",
        "network-partition-3",
        "network-partition-4"
    ],
    "properties":[
        {
            "key1" : "value1"
        },
        {
            "key2" : "value2"
        }
    ]
}

I have implemented two network partitions algorithms.

   - one-after-another : Stratos will create 1st application instance in
   network-partition-1, 2nd instance in network-partition-2 and so on.
   - all-at-once : Stratos will create application instances per network
   partitions in parallel

Properties can be used to send additional information to algorithms.

Thanks.
