 Each key could has labels. labels indicates a unique key.
 A key "log_level" with labels "env=production" 
 may saves the value "INFO" for all application log level in production environment.

 ## Why use kie
-kie is a highly flexible config server. Nowadays, an operation team is facing diffrent "x-centralized" system.
-For example a classic application-centralized system.a operator want to change config based on application name and version, then the label could be "app,version" for locating a app's configurations.
-meanwhile some teams manage app in a data center, each application instance will be deployed in a VM machine. then label could be "farm,role,server,component" to locate a app's configurations.
-kie fit diffenrent senario for configuration management which benifit from label design.
