    This method will make two passes checking for namespaces to delete. The

    deletion (ie it is empty). The period of sleep and the 2nd pass allow
    time for the namespace state to settle, so that the check prior deletion
    will re-confirm the namespace is empty.

    The utility is designed to clean-up after the forced or unexpected
    termination of Neutron agents.

    The --force flag should only be used as part of the cleanup of a devstack
    installation as it will blindly purge namespaces and their devices. This
    option also kills any lingering DHCP instances.
