This script initializes and starts a cloud task consumer server and a data
transfer process.

The script uses threading to run an ASGI server for handling cloud tasks
concurrently with a data transfer operation. The data transfer is managed 
by the TransferController, which orchestrates the retrieval and storage of 
data from the Google Cloud Data Catalog to BigQuery.

Functions:
- main: Initializes and starts the cloud task consumer and data transfer 
  process.
