To use this support in Spring Boot, configure configprop:logging.log4j2.config.override[] with the locations of one or more secondary configuration files.
The secondary configuration files will be merged with the primary configuration, whether the primary's source is Spring Boot's defaults, a standard location such as `log4j.xml`, or the location configured by the configprop:logging.config[] property.
NOTE: Log4j2 override configuration file locations can be prefixed with `optional:`, for example, `optional:classpath:log4j2-override.xml`, to indicate that the location is optional and should only be loaded if the resource exists.
