Adds integration tests for ansible operator

The tests are migrated from github.com/water-hole/ansible-operator, with
some updates and minor improvements.

Adds two new travis jobs to run the ansible-related tests. Adds artifacts that
are required to build the ansible operator base image, which will find a more
permanent home soon.
