/**
* Base class for the log cleaning function inside the master. By default, three
* cleaners: TimeToLiveLogCleaner,
* TimeToLiveProcedureWALCleaner and
* ReplicationLogCleaner are called in order. So if other effects
* are needed, implement your own LogCleanerDelegate and add it to the
* configuration "hbase.master.logcleaner.plugins", which is a comma-separated
* list of fully qualified class names. LogsCleaner will add it to the chain.
*
* HBase ships with LogsCleaner as the default implementation.
*
* This interface extends Configurable, so setConf needs to be called once
* before using the cleaner. Since LogCleanerDelegates are created in
* LogsCleaner by reflection. Classes that implements this interface should
* provide a default constructor.
