Enable home directory backups with Azure File backups

[yuvipanda]

We use Azure File storage for home directories on Azure. It offers a built in backup solution which we should enable and configure for all our deployments.

Configuration options

Given these are disaster recovery backups, let's start by keeping a 5 day daily backup.

So we:

1. backup daily
2. retain for 5 days
3. Specify window of 22:00:00 (UTC-07:00) (this matches the EFS default window)

There seem to be direct correlation with usable config properties in https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/backup_policy_file_share

Tasks

Beta Give feedback

1. Enable Azure File backups via Terraform (https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/backup_policy_file_share)
2. Deploy this to the UToronto cluster
3. Deploy this to the pchub cluster

I am not sure if I have access to the Azure account the pchub is deployed to?

@sgibson91 ah, sorry - password for that should be in bitwarden!
