Ivan Halomi 4ce47e2250 Refactor of kolla_container_facts
Refactor that prepares kolla_container_facts
module for introducing more actions that will be moved
from kolla_container module and kolla_container_volume_facts.

This change is based on a discussion about adding a new action
to kolla_container module that retrieves all names of the running
containers. It was agreed that kolla-ansible should follow Ansible's
direction of splitting modules between action modules and facts
modules. Because of this, kolla_container_facts needs to be able
to handle different requests for data about containers or volumes.
