I'm in the process of making changes to our log4j2.properties file for logstash and was wondering if there was a way to trigger the running of the log4j2 rules via a Unix signal, perhaps `kill -3` or some such. It would be helpful to be able to manually trigger the running of these configurations when debugging changes to them to see if they're getting applied/picked up correct.

Specifically I'm adding some configurations which will delete rotated files from my `/usr/share/logstash/logs` directory based on either age or size.

```
appender.rolling.type = RollingFile
appender.rolling.name = plain_rolling
appender.rolling.fileName = ${sys:ls.logs}/logstash-${sys:ls.log.format}.log
appender.rolling.filePattern = ${sys:ls.logs}/logstash-${sys:ls.log.format}-%d{yyyy-MM-dd}-%i.log.gz
appender.rolling.policies.type = Policies
appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
appender.rolling.policies.time.interval = 1
appender.rolling.policies.time.modulate = true
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = [%d{ISO8601}][%-5p][%-25c] %-.10000m%n
appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
appender.rolling.policies.size.size = 100MB
appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.action.type = Delete
appender.rolling.strategy.action.basepath = ${sys:ls.logs}
appender.rolling.strategy.action.condition.type = IfFileName
appender.rolling.strategy.action.condition.glob = logstash-${sys:ls.log.format}-*
appender.rolling.strategy.action.condition.nested_condition.type = IfAny
appender.rolling.strategy.action.condition.nested_condition.lastMod.type = IfLastModified
appender.rolling.strategy.action.condition.nested_condition.lastMod.age = 7D
appender.rolling.strategy.action.condition.nested_condition.fileSize.type = IfAccumulatedFileSize
appender.rolling.strategy.action.condition.nested_condition.fileSize.exceeds = 5GB
```
