Add pipeline details (extractor,loader and transform) into tags
Closes #5 (closed)
This MR only addresses adding pipeline details into tags. Extracting transform(dbt) tags from transform models does not seem a very nice idea because of two reasons.
- As dbt models allow adding any number of tags, rendering all these tags in airflow might make the UI a bit messy.
- There are usually a number of dbt models associated with a tap transform, it will again make the number of tags very high in airflow.
