Azure key management plugin using Key Vault

Currently there is an encryption key management plugin for AWS using KMS. It would be nice if similar functionality could be implemented for Azure.

Azure has Key Vault (https://azure.microsoft.com/en-us/services/key-vault/), which can be accessed using either the Azure CLI (https://docs.microsoft.com/en-us/cli/azure/overview?view=azure-cli-latest) or a REST API (https://docs.microsoft.com/en-us/rest/api/keyvault/) and seems to provide similar functionality to AWS KMS.
