Byron McCollum 9b70549c4a Remove cached facts in teardown.sh
Leaving cached facts around after running teardown.sh might cause
unforseen issues when re-running the playbooks. This ensures these
facts are removed as part of the teardown.sh script.

WARNING: This is a destructive action.
All containers will be destroyed as well as the data within the
containers (even if the containers are added by users and not by
AIO). Data will be removed from the host as well (e.g. files, apt
packages and pip packages). Please check this script for information
about the data to be removed in removed_(files/packages/pip-packages).
/etc/openstack_deploy will be preserved and may be manually removed
if needed.
ALL the data stored in the lvm volume group called "lxc" WILL BE
DELETED as well (even if volumes are created by users and not AIO).
Please verify that you have backed up all important data prior to
proceeding with the teardown script.
-----------------------------------------------------------------------------
To REALLY destroy all containers and delete all data mentioned above,
type 'Y' or 'y' and press enter:
