Fixes connection caching issues with Redfish BMCs where AccessErrors were
previously not disqualifying the cached connection from being re-used.
Ironic will now explicitly open a new connection instead of using the
previous connection in the cache. Under normal circumstances, the
``sushy`` redfish library would detect and refresh sessions,
however a prior case exists where it may not detect a failure and contain
cached session credential data which is ultimately invalid, blocking
future access to the BMC via Redfish until the cache entry expired or
the ``ironic-conductor`` service was restarted. For more information
please see `story 2009719 <https://storyboard.openstack.org/#!/story/2009719>`_.
