 - Added configurations to enable more `client.disconnected` events (and counter bumps) [#9267](https://github.com/emqx/emqx/pull/9267).
   Prior to this change, the `client.disconnected` event (and counter bump) is triggered when a client
   performs a 'normal' disconnect, or is 'kicked' by system admin, but NOT triggered when a
-  stale connection had to be 'discarded' (for clean session) or 'takenover' (for non-clean session).
-  Now it is possible to set configs `broker.client_disconnect_discarded` and `broker.client_disconnect_takenover` to `on` to enable the event in these scenarios.

 - For Rule-Engine resource creation failure, delay before the first retry [#9313](https://github.com/emqx/emqx/pull/9313).
   Prior to this change, the retry delay was added *after* the retry failure.

 - 为更多类型的 `client.disconnected` 事件（计数器触发）提供可配置项 [#9267](https://github.com/emqx/emqx/pull/9267)。
