Add support for ConfigurationStore values

[theunrepentantgeek]

ASO v2 already has support for AppConfiguration - we should add support for the child resource KeyValues as requested via Slack.

We should also investigate support for Replicas and Private EndpointConnections.

This would be nice to have for the use case when some of the key values are related to other resources managed with ASO and given that no native solution exists to cover it (like external secrets for secrets syncing to Azure Key Vault).

No change from the above.

Add support from Microsoft.AppConfiguration version 2024-06-01 for the following resources:

• configurationStores/keyValues
  • value should be optionally configurable from a configmap
• configurationStores/replicas
• configurationStores/snapshots
