[FLINK-6859][table] remove delete useless times for improve
StateCleaningCountTrigger
----
> StateCleaningCountTrigger should not delete timer
> -------------------------------------------------
>
> Key: FLINK-6859
> URL: https://issues.apache.org/jira/browse/FLINK-6859
> Project: Flink
> Issue Type: Improvement
> Components: Table API & SQL
> Affects Versions: 1.3.0
> Reporter: Fabian Hueske
>
> The {{StateCleaningCountTrigger}} which is used to clean-up inactive state
> should not delete timers, i.e.. not call {{deleteProcessingTimeTimer()}}.
> This is an expensive operation.
> We should rather fire the timer and check if we need to clean the state or
> not.
> What do you think [~sunjincheng121]?
