General availability: Azure IoT Gateway SDK

The Azure IoT Gateway SDK entered general availability in its [November release](https://azure.microsoft.com/en-us/blog/azure-iot-gateway-sdk-general-availability-release/). Developers can now create on-premises gateways that allow their IoT solutions to do more: connect purpose-built and legacy devices without replacing existing infrastructure, run analytics on the edge, perform time-sensitive decisions by minimizing latency, and enforce security and privacy constraints.
