Fix AZP tests, add current_container_facts module (#48)

* Add new facts module for determining whether the module is running inside a container or not.

* Add containers to main network.

* Fix running tests locally with newer docker.

* Simplify setup_openssl to only install cryptography.

* Add alias in network.

* Make sure to upgrade cryptography to something more sensible on Ubuntu 16.04.

* Don't jump through hoops for bridge.

* Try to use other IPv4 nets.

* Improve module docs.
