NIFI-1586 Implements autopurging of transaction log and snapshot files 

When NiFi is clustered, and autopurge.purgeInterval is greater than 1, the DatadirCleanupManager will be started in order to automatically purge transaction log and snapshot files based on the autopurge settings in zookeeper.properties

This closes #1928.
