The replication janitor thread is not stopped correctly when teh server is stopped

When the server is stopped, we don't stop the replication janitor thread :

jvm 1    | java.lang.InterruptedException: sleep interrupted
jvm 1    |      at java.lang.Thread.sleep(Native Method)
jvm 1    |      at org.apache.directory.server.ldap.replication.provider.ReplicaEventLogJanitor.run(ReplicaEventLogJanitor.java:164)
wrapper  | JVM exited unexpectedly while stopping the application.

This is not clean
