This adds the ansible playbooks required by kayobe to the manifest by
using the data_files option in setuptools. When using pip to install
kayobe into a virtualenv, these files will be placed in
<venv>/kayobe/share/.

In an editable install, e.g using `pip install -e .`, data_files are not
installed into the virtualenv. Instead, we must follow the egg-link file
to find out the actual location.
