azurerm_cosmosdb_account does not support backup storage redundancy

[xsatishx]

When you configure Cosmos DB there is an option to set "Backup storage redundancy" having three values

1. Geo-redundant backup storage
2. Zone-redundant backup storage
3. Locally-redundant backup storage

The terraform resource for Cosmos DB under the backup block just supports the following

A backup block supports the following:

1. type - (Required) The type of the backup. Possible values are Continuous and Periodic. Defaults to Periodic.
2. interval_in_minutes - (Optional) The interval in minutes between two backups. This is configurable only when type is Periodic. Possible values are between 60 and 1440.
3. retention_in_hours - (Optional) The time in hours that each backup is retained. This is configurable only when type is Periodic. Possible values are between 8 and 720.

There is no option to leverage Zone-redundancy and it defaults to Geo-redundancy by default.

This would result in data sovereignty issues. There needs to be a 4th option under the backup block to let us choose "zone_redundancy"

For some time I thought I might be doing something wrong, then I found this thread. Hopefully they add that feature soon
