Overview:

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:

• test_rollback_to_stable15.py
• test_rollback_to_stable16.py
• test_rollback_to_stable17.py

Tasks:

1. The tests 15-17 need to be extended by adding the in-memory scenarios.
2. The rest of the existing rollback to stable tests 1-14 also need to be extended by adding the column store scenarios.
