Generic inventory and playbook

This patch introduces the capacity for the tripleo_entrypoint.sh
script to generate an inventory and/or a playbook from env
variables passed to the runner container by the operator itself

The ansibleee-operator will take care of filling the contents of the
env variables in [1] and [2]
