Total and per-user network throttlers are never

The total and per-user network throttlers are never reset, which ensures that max_network_bandwidth_for_all_users and max_network_bandwidth_for_all_users limits are never exceeded. #81729 (Sergei Trifonov).
ClickHouse now ensures that total and per-user network throttlers are never reset, maintaining strict enforcement of network bandwidth limits.

Why it matters

This feature solves the issue where network throttling limits could be bypassed due to periodic resets of throttlers. By never resetting the total and per-user throttlers, it guarantees that the configured limits for max_network_bandwidth_for_all_users are strictly enforced, preventing users from exceeding their allotted network bandwidth over time.

How to use it

Users can apply this feature by configuring the max_network_bandwidth_for_all_users and related settings as usual. The throttling mechanism will now continuously enforce these limits without resets, requiring no additional action.
