[CES-36] - Unify terraform state files location

[christian-calabrese]

Motivation and Context

Terraform state files are currently placed in different storage accounts.
Starting from io-infra, it is necessary to unify the location of those state files and place them in Italy North.

Major Changes

Pointing all the terraform configurations of io-infra to the storage account in Italy North called iopitntfst001

Dependencies

Testing

Documentation

Other Considerations

⚠️ It is important to run the following script to actually copy the state files to the new storage accounts before merging this PR:

#!/bin/bash

# Variables - Set your own values here
DEST_STORAGE_ACCOUNT_NAME="iopitntfst001"
DEST_CONTAINER_NAME="terraform-state"

# Array of state files with corresponding source storage account and container
# Format: "source_storage_account_name:source_container_name:state_file_name"
STATE_FILES=(

The `azurerm_app_service_plan` resource has been superseded by the
`azurerm_service_plan` resource. Whilst this resource will continue to be
available in the 2.x and 3.x releases it is feature-frozen for compatibility
purposes, will no longer receive any updates and will be removed in a future
major release of the Azure Provider.
