Pulp

A quick look at the tasks in ansible-pulp that need check_mode:

• command
• shell
• script

Shows that they do not have the appropriate lines (check_mode: false usually) (corrected this description from true) so that ansible can be run in check mode (--dry-run). i.e., the tasks that don't modify the system will not run at all, but later tasks depend on them, and will fail (or behave differently.)

Check Mode is a feature that users sometimes use, so we should fix these tasks.

Our molecule-based CI does not catch this, because no part of it, not even converge, uses check_mode: https://github.com/ansible-community/molecule/issues/128
