Expected Behavior

Feast Java feature servers should be able to read from a registry in Azure blob storage.

Current Behavior

Azure users can use the python feature server through https://github.com/Azure/feast-azure/tree/main/cluster/sdk or use an old Spark centric approach for feature serving. We should enable Java serving support as well

Possible Solution

https://github.com/feast-dev/feast/blob/master/java/serving/src/main/java/feast/serving/config/RegistryConfig.java#L48 has AWS/GCP equivalents. We should implement the interface for Azure.
