trait PersistentTimers extends OnWatermark with OnInit

Per-Key Persistent Timers inspired by Flink's ProcessFunction: https://ci.apache.org/projects/flink/flink-docs-stable/dev/stream/operators/process_function.html

Note: Timers are based on a sorted RocksDB KeyValueStore Note: Timers that fire at the same time MAY NOT fire in the order which they were added
