Methods within ConversionHost#ansible_playbook were broken because certain calls to the ansible_playbook method are missing arguments. Originally part of https://bugzilla.redhat.com/show_bug.cgi?id=1622728, splitting it out to try to keep things more manageable. Already merged in master: https://github.com/ManageIQ/manageiq/pull/18323
To reproduce simply attempt to call any method that calls the ansible_playbook method, e.g. ConversionHost#disable_conversion_host_role.
Fixed! Verified on: 5.11.0.8.20190611155126_01e077e Please note 5.11.0.8 don't have v2v-conversion-ansible package and hence migration not working with that but I have installed package manually and migration is working. We are tracking that issue under BZ1720614.
