fix constructed functionality in openstack inventory plugin

The compose, groups, and keyed_groups functionality of the openstack
inventory plugin was broken:

- the plugin was not passing the correct variables to the
  Constructable methods for compose and groups
- the plugin was simply never calling the appropriate method for
  implementing keyed_groups

This commit fixes both issues.
