Description
Currently, only notifications for whole config changes are being fired (in org.apache.logging.log4j.core.LoggerContext#setConfiguration), but since particular loggers are allowed to be changed (i.e.: through JMX, which calls org.apache.logging.log4j.core.LoggerContext#updateLoggers), there should be a way to be notified about those changes too.
The fired event should ideally contain specific information about what logger(s) changed and what change it was.
