Enterprise BI Reference Architecture

Publish a module to Terraform Registry that helps to deploy the enterprise BI reference architecture, using SQL Data Factory.

Documentation about this reference architecture is [here](https://docs.microsoft.com/en-us/azure/architecture/reference-architectures/data/enterprise-bi-adf).

Terraform resources for SQL Data Factory:
- https://www.terraform.io/docs/providers/azurerm/r/data_factory.html
- https://www.terraform.io/docs/providers/azurerm/r/data_factory_pipeline.html

Start with the linked Azure enterprise BI reference architecture and the azurerm data_factory and data_factory_pipeline resource documentation. Define the Terraform module scope from those references, then verify that it deploys the requested architecture and is suitable for publication to the Terraform Registry.
