pip: false positive [DEPRECATION WARNING]: Invoking "pip" only once while using a loop via squash_actions

[ssbarnea]

SUMMARY

[DEPRECATION WARNING]: Invoking "pip" only once while using a loop via
squash_actions is deprecated. Instead of using a loop to supply multiple items
and specifying name: "{{ item }}", please use name: ['pip', 'setuptools', 'pbr'] and remove the loop. This feature will be removed in version 2.11.

      with_items:
        - "--user"

EXPECTED RESULTS

No warning should be seen. Warning implementation was incorrect as it assumed that if you loop on pip tasks you loop for packages.

Your task, and the warning do not align. That task isn't the one generating the warning. The one generating the warning is doing a loop over ['pip', 'setuptools', 'pbr'], which your task in steps to produce does not.

I tested the task you list above, and it does not cause this warning.
