public final class BackwardsCompatibilityJournalGenerator
Generates journals for consumption by the BackwardsCompatibilityIntegrationTest.
1. starts a new cluster
2. runs all the test operations listed in OPS
3. takes a journal backup at stores it to src/test/resources/old_journals
4. stops the cluster
5. copies the journal to src/test/resources/old_journals
Later, BackwardsCompatibilityIntegrationTest will start clusters from the backups and copies
in old_journals, and validate that the operations' checks pass.
Generates journal files to be used by the backwards compatibility test. The files are named
based on the current version defined in ProjectConstants.VERSION. Run this with each release,
and commit the created journal and snapshot into the git repository.
