Subject: [PATCH 12/12] Issue 4778 - RFE - Add changelog compaction task in
1.4.3
Description: In 1.4.3 the replication changelog is a separate database,
so it needs a separate "nsds5task" compaction task (COMPACT_CL5)
relates: https://github.com/389ds/389-ds-base/issues/4778
ASAN tested and approved
