* Allows user to configure a mysql ingestion job to allow replacement of the record's value for an existing record in the table. * Also replaces a backward iteration of ResultSet() with forward iteration in MySqlWriterCommands 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 - [X] 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-XXX] My Gobblin PR" - https://issues.apache.org/jira/browse/GOBBLIN-1584 ### Description - [X] Here are some details about my PR, including screenshots (if applicable): We only support insertion of new values into tables, not update/upsert. If you run an ingestion job with a record containing a record with the same primary key the whole job will fail because of the duplicate entry. We don't expect ingestion jobs to always contain only new records, so we should handle duplicate entries, ingestion of data already in the table or updates to old values. The insert vs. replace logic should be configurable to the user as well. ### Tests - [X] My PR adds the following unit tests __OR__ does not need testing for this extremely good reason: It adds a unit test that utilizes replace logic in the JdbcPublisherTest. I have also tested manually by copying duplicate data and repeated primary keys into a Mysql table and verified the values were updated. ### Commits - [X] My commits all reference JIRA issues in their subject lines, and I have squashed multiple commits if they address the same issue.
