[SPARK-24552][CORE][SQL][BRANCH-2.3] Use unique id instead of attempt…
… number for writes . This passes a unique attempt id instead of attempt number to v2 data sources and hadoop APIs, because attempt number is reused when stages are retried. When attempt numbers are reused, sources that track data by partition id and attempt number may incorrectly clean up data because the same attempt number can be both committed and aborted. Author: Marcelo Vanzin <email@example.com> Closes #21615 from vanzin/SPARK-24552-2.3.
