exporter crashes on NoneType data_items

[epleterte]

When looping through data_items from entity_stats it appears some items are NoneType in my environment. This causes the exporter to crash and die.

I get this error in the logs:

2019-06-25T10:24:39+0000 ERROR    Exiting: invalid arguments! could not register collector for ['10.0.0.1']::'NoneType' object has no attribute 'keys'

After some debugging, I can see that entity_stats is a list of dicts, but some entries are coming back as NoneType . After some of these NoneType entries, I see dicts again, and later more NoneType entries.

@epleterte For this issue, can you share the complete exporter logs, it will be helpful to reproduce the crash, sys.exit() has already been added for such case, but logs will give more clarity.

@epleterte Forgot to mention, please also include the environment and which mode you are running exporter in(container, k8s or script).
