added air_dialogue
UPDATE2 (3797ce5): Updated for multi-configs 

UPDATE (7018082): manually created the dummy_datasets. All tests were cleared locally. Pushed it to origin/master

DRAFT VERSION (57fdb20):  (_no longer draft_)
Uploaded the air_dialogue database. 
dummy_data creation was failing in local, since the original downloaded file has some nested folders. Pushing it since the tests with real data was cleared. Will re-check & update via manually creating some dummy_data
