Description

In SalesforceExtractor class, we instantiated BulkConnection directly.

      this.bulkConnection = new BulkConnection(config);

This code makes it is impossible to inject a customized BulkConnection.
In contrast, httpClient was instantiated in a function. We could extend the class and override the function to return a customized httpClient (GaapHttPClient in our case)

We should add a function to instantiate the BulkConnection.
