Removes Host Cleanup from Container Cleanup Script

Split the content of cleanup-containers into containers cleanup and host
cleanup. This allows to run the cleanup-containers from OSX clients,
while keeping needed code to delete host artifacts left behind by the
neutron agents container.

In addition, cleanup-containers may disappear in the future, replaced by
a docker-compose wrapper.
