   **Description**
   
   <!-- A short description of your feature -->
   Currently, we compare entire Serialized blobs to determine if the DAG 
changed or not before we write the Serialized DAGs to the Database which can be 
expensive.
   Instead, we will store the HASH / SHA of the Serialized JSON and store that 
in a separate column in the serialized_dag table.
   And before writing the Serialized Blob, we will compare the SHA to decide if 
DAG changed.
