Principle

• Minimize user operations for managing and monitoring topologies
• REST Service centralized metadata management
• Consistent UI experience

Objective

1. Make sure consistent semantics between the term application (user space) and topology (physical space only)
2. Topology should read configuration from SiteApplicationEntity#config instead of configuration file
3. 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 
4. Eagle UI should support to manage/monitor the application on site/application page
5. Single site/application may have more than one topologies (for example hdfsAuditLogMonitoring and userProfileMonitoring should have topologies running separately)
