fixes:
- Ironic does not monitor the socat proxy started for serial console
access. The socat process would exit on client disconnect, which
would (a) leave a zombie socat process in the process table and (b)
disable any subsequent serial console connections. Fixed the issue by
updating Ironic to call socat with the ``fork,max-children=1`` options,
which makes socat persist and accept multiple connections (but only one
at a time). See https://storyboard.openstack.org/#!/story/2005024.
