Add TASK_MANAGER_LOCK_TIMEOUT (#15300)

Browse Source 
* Add TASK_MANAGER_LOCK_TIMEOUT

`TASK_MANAGER_LOCK_TIMEOUT` controls the `idle_in_transaction_session_timeout` and `idle_session_timeout` configuration for task manager connections and lock in database

hope to prevent the situation that the task instance that holds the lock becomes unresponsive and preventing other instance to be able to run task manager

* Add session timeout to periodic scheduler and all sub task manager locks
