Make desired objects in fed controller reconcilation function fully writable
When creating desired objects for sub-cluster in reconciliate functions we don't make full copies. This may result in unexpected race condition in the future when someone actually adds some object modifications (not needed in most cases but anyway - the cost of extra copy will be relatively small comparing to inter-cluster traffic). In case of ReplicaSet and Deployment the spec copy was a shallow one - ok for setting just replicas but also error-prone in the future.

Federated deployment controller - part 1
Based on federated replicaset controller (copy + find/replace).
Remaining stuff:
- refacing out common elements to libs
- using owerref in pod analysis
- e2e tests
- renaming concurrency flag for rs and reusing it in deployment
- updating only one cluster at a time if rollingupdate strategy is used.

Use hash in federated replica set planner
Without this all replicaset of size 1 would land in the same cluster if the default preferences (weight=1) are used.

Support for preexisting replicas and estimated capacity in federated replicaset controller
With this PR the planer will be able to:
* Keep already existing replicas in their current clusters if rebalance = false and min/max boundaries are met.
* Limit the number of replicas in a cluster to the level that was measured by the count of running and unschedulable pods. And provide an estimate how much more pods would be nice to put in a cluster so that if they are scheduled we will be closer to the desired layout or to schedule the desired number of replicas at all.
