Review comment:
If we keep this method, we need to add a map in `StreamTask` to store the
corresponding `ProcessingTimeService` of all operators. In order to properly
handle `quiesce` of `ProcessingTimeService`, the `ProcessingTimeService`
obtained by passing the same `operatorIndex` must always be the same. The idea
of introducing `ProcessingTimeServiceAware` is to store the
`ProcessingTimeService` object in the operator. What do you think? @pnowojski
