Issue XD-3080: Add support for cluster rebalancing
When deploying streams to clustered Spring XD modules are deployed to all avilable Spring XD containers (assuming no additional deployment properties are specificed). Each container gets similar number of modules. When Spring XD container departs from the cluster all departing modules will be migrated to remaining containers. After container rejoins the cluster the modules are not redeployed to it and the cluster looks unbalanced and the node is not used. !unbalanced-cluster.png!
