> FLINK-25387 introduced an {{ExecNodeContext}} which contains all information to generate unique and deterministic identifiers for all created {{Transformation}}.
> This issue includes:
> - Add {{ExecNodeContext.generateUid(operatorName: String): String}}
> - Go through all ExecNodes and give transformations a uid. The name can be constant static field within the ExecNode such that both annotation and method can use it.
> - We give all transformations a uid, including stateless ones.
> - The final UID should look like: {{13_stream-exec-sink_1_upsert-materializer}}
