    Integrate undercloud_user var int oooq

    We need to differentiate local_working_dir from working_dir
    as well as decouple the stack user from `ansible_user` var.
    Both of these are causing issues as we begin to automate
    deployments in more environments.

    - update common/defaults to use undercloud_user
    - make tripleo-inventory inherit from common role, pull
      duplicate vars out of its defaults
    - make convert-image inherit from common role, update
      template to use undercloud_user
    - update libvirt/setup/undercloud to use undercloud_user
