WatcherDispatcher for federated controller tests
This PR fixes a problem when 2 informers create a watch for the same resource using the same client. Previously only one informer would receive updates.

quinton-hoole: To provide some more context to those doing cherrypicking, the bug that this PR fixes makes federated unit tests fail intermittently, and generally behave very poorly.

Verified manually that I can delete federation namespaces now.
Will update federation-namespace e2e test to verify that namespace is deleted fine

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.

Clean-up and fixes in federated replica set
* Create and update consistent with other controllers. Previously an annotation update on federated rs would not trigger local rs update.
* Use of federatedUpdater. The previous code use talked to clusters manually, assuming that the stats values in the local rs would be automatically and immediately updated. These stats are updated by controllers so they are not immediately updated and the currently existing stats can be used for building federated rs stats.
* Trigger a rs recheck after some operations are executed.

ObjectMeta equivalence in federated controller handlers + update in fed secrets
Federated secrets should trigger also on data/type update, not only on object meta.

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.
