When this module was written back in May 2015 we were using 1.9.x. Being lazy I added to param the objects that the other functions would need. What I have noticed is in 2.0 exit_json is trying to jsonify those complex objects and failing. This PR resolves that issue with the vmware_cluster module.
@kamsz reported this issue in https://github.com/ansible/ansible-modules-extras/pull/1568
