[DEV-11187] Adds new List Database Downloads Endpoint

[collinwr]

Description: Create a new endpoint api/v2/bulk_download/list_database_download_files/ that returns urls for both the full and subset database downloads.

Technical details:

• In order to get this to run locally, I added a line to the minio docker-compose.yml setup to create the bulk_download bucket locally.
• No API document is included because this will not be a public API. It is meant to be used by Salesforce only.
