Azure Key Vault Client Libraries for Python

The `azure-keyvault` library provides client access to Azure Key Vault, a cloud service for securely storing and accessing secrets, keys, and certificates. It offers distinct clients for managing each resource type within the unified `azure-keyvault` umbrella package. As part of the Azure SDK for Python (Track 2), it integrates with `azure-identity` for authentication. The current stable version is 4.2.0, with minor updates typically released on a bi-annual basis.
