Description

Added the AtomicBarrier and PhaseLockingTestMixin, the initial building blocks of the Concurrency Testing framework, in order to make way to add a Suite that tests the interaction of the ConflictChecker with the RowTracking feature, ensuring Row Tracking is well-tested and getting ready for enabling Row Tracking outside of testing in Delta.

How was this patch tested?

Added UTs.

Does this PR introduce any user-facing changes?

No.
