Subject: [PATCH] implement reset for podman driver (#269)

* implement reset for podman driver

* when the podman driver runs the `create` playbook, we'll add a
  `owner=molecule` label to the containers we create
* in `reset`, we'll delete containers (eventually everything?) that has
  the label `owner=molecule`

* address PR feedback

* hotfix filter/labels typo
* use `label` instead of alias `labels`
