HTTP 500 error calling Foundation 5.5 to image nodes in module 1.9.1

[jtroyj]

When trying to use module 1.9.1 to image nodes via Foundation 5.5 the following error occurs:

TASK [Image nodes using manual and discovery modes] ********************************************************************
fatal: [localhost]: FAILED! => {"changed": false, "error": "HTTP Error 500: INTERNAL SERVER ERROR", "msg": "Failed fetching URL: http://10.38.222.245:8000/foundation/image_nodes", "response": null, "status_code": 500}

The error is easily reproducible with the sample foundation yaml just by defining the Foundation 5.5 host and running the playbook.

We would expect that the playbook would be able to initiate node imaging.

Just as an FYI the same playbook kicked off properly against a Foundation VM running 5.2.2.
