Update ecommerce database configuration

Created by: xitij2000

The Ansible variables for ecommerce database configuration have changed such that Ocim can no longer deploy an instance based on the standard edx/configuration repo.

This change adds variables to support the new variables for configuring ecommerce.

Sandboxes:

edx:master:

• LMS: https://ocpr268.sandbox.stage.opencraft.hosting/
• Studio: https://studio-ocpr268.sandbox.stage.opencraft.hosting/
• Ecommerce: https://ecommerce-ocpr268.sandbox.stage.opencraft.hosting/

open-craft:opencraft-release/ginkgo.1

• LMS: https://ocpr268-ginkgo.sandbox.stage.opencraft.hosting/
• Studio: https://studio-ocpr268-ginkgo.sandbox.stage.opencraft.hosting/
• Ecommerce: https://ecommerce-ocpr268-ginkgo.sandbox.stage.opencraft.hosting/

Merge deadline: None

Testing instructions:

1. Set up an Ocim instance based on this pull request.
2. Create an instance based on edx/configuration:master and edx/edx-platform:master
3. Launch an AppServer for that instance
4. If all else works, the ecommerce configuration step should not fail during database migrations.
