Automate Remaining Failure/Cancellation Tests

We've already automated a lot of failure tests. See the related regression test schedule [here](https://github.com/citusdata/citus/blob/master/src/test/regress/failure_schedule)

I'm listing the ones that are remaining.

- [ ] Deadlock detection
- [ ] 2PC recovery
- [x] Tenant isolation
- [x] master_move_shard_placement -> w/wout logical replication
- [x] MX metadata sync
