Is your feature request related to a problem? Please describe. This is not directly tied to a problem but rather a feature request to enhance Spring Cloud Config Server. Currently, Azure Key Vault is not natively supported as a backend, which could simplify configuration management in Azure-based environments.

Describe the solution you'd like I would like Spring Cloud Config Server to natively support Azure Key Vault as a backend, enabling it to fetch configuration properties directly and securely without requiring custom implementations.

Describe alternatives you've considered Writing a custom EnvironmentRepository to integrate with Azure Key Vault.
