3507e96b3d CVE-2021-3670 ldap_server: Clearly log LDAP queries and timeouts
This puts all the detail on one line so it can be searched
by IP address and connecting SID.

This relies on the anr handling as otherwise this log
becomes the expanded query, not the original one.

RN: Provide clear logs of the LDAP search and who made it, including
a warning (at log level 3) for queries that are 1/4 of the hard timeout.

Windows behaviour by sending a LDAP exop response with msgid 0 that is
