Python IoT Hub

This gist is an attempt to design a Python API to implement a distributed IoT solution composed of:

• Several IoT Device and Station backends (Examples: (BLEDevice, BLEStation), (OPCUADevice, OPCUAStation), ...)
• A single IoT Gateway implementation, which can be deployed as different instances, potentially running different backends.
• A single IoT Hub service running somewhere in the cloud
• A single IoT Hub client implementation which can be used by Python developers
• Two wrappers RemoteDevice and RemoteStation useful when interacting with IoT devices and stations

Install azure-cli (ansible task file)

This gist describes how to install azure-cli with Ansible.

Disclaimer: Code has not been tested so it may not work, but the intent is still clear.

Reference: Azure/azure-cli#20476 (note that issue has been opened by an engineer working at Microsoft on Azure CLI, so I take it as "it's ok to install azure-cli with pip assumning you don't have problem with using Pypi".)
