Azure Management Core Library for Python

The `azure-mgmt-core` library provides extensions to Azure Core that are specific to Azure Resource Management (ARM), primarily used by Azure SDK management client libraries (e.g., `azure-mgmt-resource`). As a foundational component, it handles common ARM-specific patterns such as long-running operations and authentication challenges. The current stable version is 1.6.0, and it follows the release cadence of the broader Azure SDK for Python.
