/**
 * Main function for using the Config Manager. The main function starts a Config Manager, and reacts to all messages thereafter
 * In order for this module to run, you have to add the following configurations to the config file:
 * yarn.rm.address=localhost //the ip of the resource manager in yarn
 * yarn.rm.port=8088 //the port of the resource manager http server
 * Additionally, the config manger will periodically poll the coordinator stream to see if there are any new messages.
 * This period is set to 100 ms by default. However, it can be configured by adding the following property to the input config file.
 * configManager.polling.interval= < polling interval >
 * To run the code use the following command:
 * {path to samza deployment}/samza/bin/run-config-manager.sh  --config-factory={config-factory} --config-path={path to config file of a job}
 *
 * @param args input arguments for running ConfigManager.
