Description

Currently, an execution is usually represented as "job vertex name (subtaskIndex+1/vertex parallelism) (attemptId)" in logs, which may be redundant after this refactoring work. With the change of FLINK-17295, the representation of Execution in logs will be redundant. e.g. the subtask index is displayed 2 times.

Therefore, I'm proposing to change the format to be "<job vertex name> {}(<subtaskIndex>+1/<vertex parallelism>) #<attemptNumber>  (graph: <short ExecutionGraphID>, vertex: <JobVertexID>) " and avoid directly display the ExecutionAttemptID. This can increase the log readability.
