   ## Description
   
   Adding ArangoDB provider based on Python SDK 
https://github.com/ArangoDB-Community/python-arango
   
   Users can create their own custom operators leveraging the **ArangoDBHook**  
directly 
   or building their operator on **AQLOperator** by providing 
**result_processor**  method,
   
   ```
   operator = AQLOperator(
       task_id='aql_operator',
       sql="FOR doc IN students " \
           "RETURN doc",
       dag=dag,
       result_processor=lambda cursor: print([document["name"] for document in 
cursor])
   )
   ```
   
   Sensor can be implemented by SQL
   
   ```
   sensor = AQLSensor(
       task_id="aql_sensor",
       sql="FOR doc IN students " \
           "FILTER doc.name == 'judy' " \
           "RETURN doc",
       timeout=60,
       poke_interval=10,
       dag=dag,
   )
   ```
