Add Controller Logging Feature
This features provides a mechanism to extend the logback.xml properties to add controller specific loggers. The controller's logger will log messages from topics that the controller listens to in a controller specific network log. The original network log is preserved and still logs every message from every controller. Note that the way a logger is associated with a controller is by having the logger name match the controller's name. Any configuration file that has "logback-include-" prepended and a ".xml" extension will be added to the logback.xml and logback-eelf.xml files as extensions to the base configuration. Issue-ID: POLICY-1427 Change-Id: Iaeb823421eadb7ee413b6b03ae3dfe862f230612 Signed-off-by: Daniel Cruz <dc443y@att.com>
