Added script for resource cleanup

Added script for resource cleanup

This script can be either run from jumphost or overcloud nodes.
If run from jumphost, it will clean all resources on all nodes as well
as openstack resources.
If run from an overcloud node, it will clean resources on that node.
The script supports whitelisting and exclusion of resources to be
cleaned.
