Description

Currently, if user have a simple request of do some alerting where the data source is well matched json to stream schema definition.
He has to write a code like KafkaStreamMonitorApp, specify the alert executor id, like what we do for HadoopJmxMetricMonitor.

This steps are good before v0.4, since at that time user need to manually start the topology. In v0.4, we have topo-mgmt, which we could encourage user to start/stop topology remotely through api/ui. We could provide/enhance to provide an sample app that consume for one policy executor id(from the config). So that for typical use case, user only need to specify the application.conf, then a topology with alert function could be started though UI without any code/jar submit.
