'Privacy' mode for logging and statistics

The problem

I would like a privacy oriented server (minimum logging), but still be able to see statistics and blocked domains (for troubleshooting and unblocking)

With privacy enabled:
The server would still generate statistics, but not capture domain names at all (so not just a filter on the output, but not captured at all)
The server would only log blocked domains (so not just a filter on the output, but not captured at all)

This would also solve #6697 I think.

For granularity there might be 2 checkboxes, 1 for logs, 1 for statistics.

Proposed solution

1 or 2 checkboxes in the 'General Settings', either Privacy mode globally, or one for Log and Statistics separately.

Enabling the log privacy would only log blocked domains, for troubleshooting/unblocking

Enabling the statistics privacy would only keep anonymous statistics (no Top [Queried|Blocked] domains stored anywhere)

Alternatives considered and additional information

Turn off statistics and logging.

Both are unsatisfactory:
No view on general statistics, total Qs, blocks, clients, etc.)
No information on blocked domains (needed for troubleshooting and unblocking)
