title: Open api specification for Azure Iothub devices
body: <p>I can't seem to find open api spec for azure iothub devices related operations. I'm talking about specifically these <a href="https://docs.microsoft.com/en-us/rest/api/iothub/service/devices" rel="nofollow noreferrer">operations</a>. I need openapi spec so that I can use <a href="https://github.com/Azure/autorest" rel="nofollow noreferrer">autorest</a> to genrate client code in golang.</p>
