Returns the network status address.
This is the address of a shared-data key that is monitored by all component instances in the cluster. When the key is set, components know that the network is considered stable. During a network configuration change, the network manager will unset the status address, notifying components that the network is no longer stable until the key is reset. This is the mechanism used by Vertigo to perform coordination between components.
@return The network status address.
