repl_meta_data: Re-work printing of replicated entries

This re-work of our LDIF printing avoids some of the privacy issue from
printing the full LDIF at level 4, while showing the entry that actually fails.

Instead, we print the DN only at level 4, then the full message at 8.

While all of the DRS replication data is potentially sensitive
the passwords are most sensitive, and are now not printed unencrypted.
