Azure Management Namespace Package

The `azure-mgmt-nspkg` library is a Microsoft Azure Resource Management Namespace Package. It is an internal package whose primary function is to establish and manage the `azure.mgmt` namespace for older versions of Azure management client libraries. As a namespace package, it does not contain any functional code, classes, or methods itself. Its current version is 3.0.2, and it follows the release cadence of the broader Azure SDK for Python, though this specific package is now largely static.
