Dear Gobblin maintainers, Please accept this PR. I understand that it will not be reviewed until I have checked off all the steps below! ### JIRA - [ ] My PR addresses the following [Gobblin JIRA](https://issues.apache.org/jira/browse/GOBBLIN/) issues and references them in the PR title. For example, "[GOBBLIN-1413] My Gobblin PR" - https://issues.apache.org/jira/browse/GOBBLIN-1413 ### Description - [ ] Here are some details about my PR, including screenshots (if applicable): Emit GMCE(Gobblin Metadata Change Event) as long as watermark moved on streaming pipeline. Currently the GMCE won't be triggered within streaming pipeline if no new file being generated. This causes problem if watermarks moved, while no file being generated(for example, data been filtered out by quality checker), GMCE will be missed. Change GMCE publisher to produce GMCE when no file generated. Change IcebergMetadataWriter to correctly update watermark. ### Tests - [ ] My PR adds the following unit tests __OR__ does not need testing for this extremely good reason: ### Commits - [ ] My commits all reference JIRA issues in their subject lines, and I have squashed multiple commits if they address the same issue.
