The "ignored" makes me think that it shouldn't actually be a problem -- 
are we assuming that's the error because of logs like 
https://c972f4bb262ae2d5c5d6-598e1d61c0aab85aa3b67b337ca2c556.ssl.cf2.rackcdn.com/749014/2/check/bifrost-integration-tinyipa-ubuntu-xenial/9d2905c/logs/ironic-inspector.log 
?

Digging down to 
https://c972f4bb262ae2d5c5d6-598e1d61c0aab85aa3b67b337ca2c556.ssl.cf2.rackcdn.com/749014/2/check/bifrost-integration-tinyipa-ubuntu-xenial/9d2905c/logs/all/syslog 
shows tracebacks like

   File ".../eventlet/hubs/__init__.py", line 39, in get_default_hub
     import eventlet.hubs.epolls
   File ".../eventlet/hubs/epolls.py", line 13, in <module>
     from eventlet.hubs.hub import BaseHub
   File ".../eventlet/hubs/hub.py", line 24, in <module>
     import monotonic
   File ".../monotonic.py", line 169, in <module>
     raise RuntimeError('no suitable implementation for this system: ' + 
repr(e))
RuntimeError: no suitable implementation for this system: 
AttributeError("'module' object has no attribute 'epolls'",)

Maybe it's worth looking at why monotonic can't find a suitable 
implementation?
