AWS IoT Core Device Advisor announces support for MQTT over WebSocket

We are excited to announce the General Availability of AWS IoT Core Device Advisor support for MQTT over WebSocket. [AWS IoT Core Device Advisor](https://docs.aws.amazon.com/iot/latest/developerguide/device-advisor.html) is a cloud-based, fully managed test capability that validates AWS IoT device software for reliable and secure connectivity with AWS IoT Core. With this update, customers can run all three test suites of AWS IoT Core Device Advisor - qualification, custom, and long duration tests - using Signature Version 4 for MQTT over WebSocket. Signature Version 4 is a protocol for authenticating inbound API requests to AWS services, in all AWS Regions. In addition, all existing connectivity and security test cases within AWS IoT Device Advisor now support MQTT3.1.1 and MQTT5 over WebSocket, making it easier for customers to validate MQTT functionality during device software development before on-boarding them to [AWS IoT Core](https://aws.amazon.com/iot-core/). AWS IoT Core Device Advisor is a regional service which is accessible globally but is hosted in US East (N. Virginia), US West (Oregon), Asia Pacific (Tokyo) and Europe (Ireland) regions.
