Release Note

Before Flink 1.12 the `KeyedStream.intervalJoin()` operation was changing behavior based on the globally set Stream TimeCharacteristic. In Flink 1.12 we introduced explicit `inProcessingTime()` and `inEventTime()` methods on `IntervalJoin` and the join no longer changes behaviour based on the global characteristic.

Description

With the deprecation of StreamExecutionEnvironment.setStreamTimeCharacteristic() in FLINK-19319 we need a way of explicitly configuring the time behaviour of these join operations. Currently, all join operations use the characteristic to configure themselves.

Alternatively, we might consider removing/deprecating these join operations.
