Associate tag1 to table1 with propagate set to True.
Since it has 2000 level lineage , the task takes times and it is in PENDING state.
Now flip the propagate flag to False at table1. There is CLASSIFICATION_PROPAGATION_DELETE task which gets completed soon.
After some time "CLASSIFICATION_PROPAGATION_ADD" gets completed.
Now tag is propagated to all entities down the 2000 level lineage.
