Updated role(s) README.md files (#1043)

* Update controller_ad_hoc_commands_cancel/README.md

The 'when' conditional in the 'Standard Role Usage' section appeared to be a copy/paste from controller_ad_hoc_command role, README.md. 

Updated to reflect the role and use within the controller_ad_hoc_commands_cancel/tasks/main.yml file.

* Update controller_bulk_job_launch/README.md

The roles section under 'Standard Role Usage' appeared to be a copy/paste from controller_license role, README.md. Updated to reflect the correct role, with the correct when conditional.
