Make sure consistent semantics between the term application (user space) and topology (physical space only)
Topology should read configuration from TopologyDescService#config instead of configuration fileconfiguration can be edited on UI
Use REST Service as only entry to manage application (START/STOP/HEALTH CHECKING) and ApplicationManager to schedule the task execution and update the execution information
Eagle UI should support to manage/monitor the application on site/application page
Single site/application may have more than one topologies (for example hdfsAuditLogMonitoring and userProfileMonitoring should have topologies running separately)
