Configure travis for unit tests (#195)

* Mark tests and add travis configuration files

* Make sure the tests dir has an __init__

* Just test for now, lint is in a bad state

* Add click dependency for travis

* Move tests for the user's .env into the e2e tests

* Bring back all the py versions

* Try removing tests/__init__.py

* Include setuptools for virtualenvs that need the update

* Revert "Try removing tests/__init__.py"

This reverts commit 83265feb83.

* Remove 3.3 and 2.6 from the python test envs

* Add Travis badge to README

 # Azure IoT Edge Dev Tool
 
+[![Build Status](https://travis-ci.org/Azure/iotedgedev.svg?branch=master)](https://travis-ci.org/Azure/iotedgedev)

 The **Azure IoT Edge Dev Tool** greatly simplifies [Azure IoT Edge](https:/azure.microsoft.com/en-us/services/iot-edge/) development down to simple commands driven by Environment Variables. 
 
  - It gets you started with IoT Edge development with the [IoT Edge Dev Container](#iot-edge-dev-container) and IoT Edge Solution Scaffolding that contains a sample module and all the required configuration files.
