/**
 * This module is reponsible for refreshing cycle chain entries for consensors
 * and archivers that are not rotating and would be "forgotten" by the network.
 * In a network that has low amount of rotation or no rotation, a syncing node
 * would have to read the cycle chain all the way back to where the oldest node
 * in the network joined. If there is no rotation, this would mean reading back
 * to the begining of the cycle chain. To avoid this we refresh the join info
 * for the consensor or archiver. Thus the syncing node has to read back much
 * less to sync the cycle chain.
