> *Background*
>  # pipeline.time-characteristic is the configuration option used to control the time characteristic for all created streams, and has the default value _PROCESSING_TIME_ at the point of writing. However, the configuration option won't take effect unless it is explicitly set by user as we read it into the code by configurtion.getOptional(xx).ifPresent(xx).
>  # The default value of _TIME_CHARACTERISTIC_ has been changed from _PROCESSING_TIME_ to _EVENT_TIME_ in FLINK-19317 Make EventTime the default StreamTimeCharacteristic - ASF JIRA (apache.org)
>  # _TIME_CHARACTERISTIC_ and the relevant operations that set or uses it have been deprecated in FLINK-19318 Deprecate timeWindow() operations in DataStream API - ASF JIRA (apache.org) and FLINK-19319 Deprecate StreamExecutionEnvironment.setStreamTimeCharacteristic() and TimeCharacteristic - ASF JIRA (apache.org)
> *Proposed Change*
>  # {*}{*}pipeline.time-characteristic should be deprecated, just like other _TIME_CHARACTERISTIC_ related operations as we no longer want user to set this.
>  # pipeline.time-characteristic should have the default value of {_}EVENT_TIME{_}, to reflect the actual default value in system, and avoid misleading users.
> Additionally, I think all configuration options which only take effect when it is explicitly set by user (aka those read into the system by configurtion.getOptional(xx).ifPresent(xx)), should have no default values.
