Fixes #37942 - Add job_check_mode to allow Ansible Check Mode in Job Templates

[bnerickson]

Overview of Changes

This PR adds a separate job_check_mode variable to the AnsibleRunner class allowing Ansible Check Mode to be set on Jobs when the new ansible_check_mode checkbox is selected in Ansible Job Templates (see PR theforeman/foreman_ansible#742).

Implementation Considerations

I considered re-using the existing check_mode variable. However, its intended use is with the ansible_roles_check_mode host parameter executing Ansible Check Mode on the "Ansible Roles" job only. Therefore, in order to not change the current expected behavior, I've separated the new functionality into a different boolean.

Testing Steps

1. Add the changes in Fixes #37942 - Adding Ansible Check Mode to Ansible Job Templates foreman_ansible#742 to your test environment.
2. Add the changes in this PR to your test environment.
3. Clone the "Ansible Roles - Ansible Default" Job Template.
4. In the clone's "Ansible" tab, select the "Ansible Check Mode Enabled" checkbox and save the Job Template.
5. On a host, schedule a Job and select the cloned Job Category and Job Template. Execute the job.
