14 * Service used to bring up/down the NativeEos service in individual datacenters.
15 * Active datacenter in native eos terms means that the candidates from this datacenter can become owners of entities.
16 * Additionally the singleton component makings ownership decisions, runs only in an active datacenter.
19 * Caller must make sure that only one datacenter is active at a time, otherwise the singleton actors
20 * in each datacenter will interfere with each other. The methods provided byt this service can be called
21 * on any node from the datacenter to be activated. Datacenters only need to brought up when using non-default
22 * datacenter or multiple datacenters.
