integration test: initial commit of integration test framework

The adds in end-to-end testing of cloud-init. The framework utilizes
LXD and cloud images as a backend to test user-data passed in.
Arbitrary data is then captured from predefined commands specified
by the user. After collection, data verification is completed by
running a series of Python unit tests against the collected data.

Currently only the Ubuntu Trusty, Xenial, Yakkety, and Zesty
releases are supported. Test cases for 50% of the modules is
complete and available.

Additionally a Read the Docs file was created to guide test
writing and execution.
