Azure Serverless Reference Architecture

Create a Terraform module that deploys a serverless reference architecture in Azure that allows event processing using Azure Function.

Documentation about this reference architecture is [here](https://docs.microsoft.com/en-us/azure/architecture/reference-architectures/serverless/event-processing).

Start by reading the linked Azure serverless event-processing reference architecture and inspecting the repository structure for existing Terraform modules. Done means a Terraform module deploys the described Azure Function-based event-processing architecture, with the module structure and usage documented in the repository.
