Soft-leader election mechanism for cc based on observed cluster state
Summary:
Every Admin node runs a CC which can act as the leader. The acting leader is decided based on deterministically sorting all admin nodes
(e.g. based on their plain node id) and picking the first alive node.
The acting leader is allowed to make control decisions (e.g. calling into the Scheduler and the LogsController).
