docs(deploy): terraform backend - remote vs local

[julie-ng]

Desired/Expected Functionality

Users who want to try this out should be able to run simple 3 command terraform init, plan and apply without having to create remote backend (Blob Storage) for Terraform state.

Problem

If you clone this repo and try to run it locally, Terraform will require that you create a remote backend because this repo uses a remote backend, see provider.tf

terraform {
  backend "azurerm" {}
  …
}

Currently the deploy docs say to use -backend=false flag, but it does not work for if it hasn't been initialised before. See https://www.terraform.io/docs/cli/commands/init.html

To skip backend configuration, use -backend=false. Note that some other init steps require an initialized backend, so it is recommended to use this flag only when the working directory was already previously initialized for a particular backend.

Solution?

Not sure. For now, updating docs to clarify would also be good.
