Add duration debug logging to the samba bind9 dlz driver and the dnsserver_common routines. This should aid future diagnosis of performance issues, and could be used to monitor DNS performance. The logs are currently Human readable text only, i.e. no JSON formatted output. Log lines are of the form: <function>: DNS timing: result: [<result>] \ duration: (<duration>) zone: [<zone>] name: [<name>] \ data: [<data>] e.g. dns_common_wildcard_lookup: DNS timing: result: [WERR_OK] \ duration: (111) zone: [] \ name: [DC=_ldap._tcp.Default-First-Site-Name._sites.ForestDnsZones,\ DC=chgdcpassword.samba.example.com,CN=MicrosoftDNS,DC=DomainDnsZones,\ DC=chgdcpassword,DC=samba,DC=example,DC=com] data: [] Enabled by setting log level to "dns:10" durations are in microseconds.
