"ease" appears to be misnamed and the line above it appears to be either a duplicate of like 46 or a typo of a command for "ease".  I found ease.yml in the ora tasks folders, but this seems to be included in the ora ansible files (line 22 in https://github.com/edx/configuration/blob/master/playbooks/roles/ora/tasks/deploy.yml.

Finally, I found a closed issue (https://github.com/edx/configuration/issues/656) that may pertain to this problem, but since the problem doesn't seem fixed perhaps something went awry.
