features:
- A new mechanism has been added to the ``neutron-netns-cleanup`` tool that
allows to kill processes listening on any ``Unix`` or network socket within
a namespace. The new mechanism will try to kill those processes gracefully
using the ``SIGTERM`` signal and, if they refuse to die, then the
``SIGKILL`` signal will be sent to each remaining process to ensure a
proper cleanup.
