`az redisenterprise` add support for active geo-replication

**Is your feature request related to a problem? Please describe.**

Support for [configuring active geo-replication](https://docs.microsoft.com/en-us/azure/azure-cache-for-redis/cache-how-to-active-geo-replication) is [missing in Azure CLI](https://docs.microsoft.com/en-us/cli/azure/redisenterprise/database?view=azure-cli-latest).

**Describe the solution you'd like**

Please add support for configuring active geo-replication via Azure CLI.

**Describe alternatives you've considered**

As of 2022-04-19, there is no way to automate the configuration of active geo-replication via Azure CLI, Terraform, or REST. The only method that appears to be available for automating this is [Bicep](https://docs.microsoft.com/en-us/azure/templates/microsoft.cache/redisenterprise/databases?tabs=bicep#databaseproperties), which we do not wish to mix with our existing Terraform.
