Provides a mechanism to allow the central agent to be horizontally scaled out, such that each agent polls a disjoint subset of resources. This is achieved through the use of `tooz` library for distributed coordination. If a service wants to use work-load partitioning, it must first create a PartitionCoordinator object and call its `heartbeat` method periodically. To distribute a set of resources over multiple agents, use the `extract_my_subset` method of the PartitionCoordinator that filters an iterable, returning only the resources assigned to us. The `PartitionCoordinator` uses `tooz` to figure out which agents are in the same group and figures out which resources belong to the current agent.
