Azure Client Runtime for AutoRest Generated Node.js Libraries

ms-rest-azure served as the foundational client runtime for Node.js Azure client libraries generated using the AutoRest toolchain. It provided essential infrastructure for handling HTTP requests, error responses, tracing, and Azure-specific authentication mechanisms such as Device Token, Service Principal, and Managed Identity. The package (version 3.0.2, last published approximately four years ago) was part of the older `azure-sdk-for-node` repository. As of March 2023, this package, along with many others in its repository, has been officially deprecated. The Azure SDK team has transitioned to a new generation of SDKs (`@azure/*` packages) that offer isomorphic capabilities (browser and Node.js support), consistent design guidelines, and native TypeScript support. Users are strongly encouraged to migrate to the newer `@azure/core-client` and `@azure/identity` packages for modern Azure development.
