Read authentication parameters from storage task

[davidmezzetti]

Currently, the storage task does not support reading authentication parameters. While this task is using the same library as embeddings cloud storage (Apache Libcloud), this is effectively limiting the task to only working with local storage.

This change will add the following parameters to the storage task (as shown in the embeddings cloud storage config reader).

# Get driver for provider
driver = get_driver(config["provider"])

# Get client connection
client = driver(
  config.get("key", os.environ.get("ACCESS_KEY")),
  config.get("secret", os.environ.get("ACCESS_SECRET")),
  host=config.get("host"),
  port=config.get("port"),
  token=config.get("token"),
  region=config.get("region")
)
