Variable and fixed-length column store support was added to rollback-to-stable in tickets
WT-5545, WT-7119 and WT-7120. The following tests were added as part of these tickets to test the column store support:
- The tests 15-17 need to be extended by adding the in-memory scenarios.
- The rest of the existing rollback to stable tests 1-14 also need to be extended by adding the column store scenarios.
