BEEN service logging into cluster.
* `BeenAppender` is a logback appender implementation
* It dynamically loads the first implementation of `ServiceLogHandler`
* This implementation has to be on the BEEN classpath
* This implementation uses a static instance of `ServiceLogPersister`
* The `ServiceLogPersister` static instance gets activated once cluster data structures are ready
* `ServiceLogPersister` guesses service names by logger package name
* Logs are committed to persistence queue
* Use `BeenApi#getServiceLogsBy*` to retrieve them
* NEEDS TESTING
