Migrate ITs to Testkit (#1214)

Migrated tests:
- `NestedQueriesIT.shouldAllowNestedQueriesInTransactionConsumedAsIterators` -> `TestIterationTxRun.test_nested`
- `NestedQueriesIT.shouldAllowNestedQueriesInTransactionConsumedAsIteratorAndList` -> `TestIterationTxRun.test_nested_using_list`
- `NestedQueriesIT.shouldAllowNestedQueriesInSessionConsumedAsIterators` -> `TestIterationSessionRun.test_nested`
- `NestedQueriesIT.shouldAllowNestedQueriesInSessionConsumedAsIteratorAndList` -> `TestIterationSessionRun.test_nested_using_list`

Deleted tests:
- `shouldAllowNestedQueriesInTransactionConsumedAsLists` -> deleted, it is effectively a sequential query execution
- `shouldAllowNestedQueriesInSessionConsumedAsLists` -> deleted, it is effectively a sequential query execution
- `CausalClusteringIT` -> deleted, unsafe cluster tests
