Ansible deprecation warning - squash_actions

[sfuerte]

Getting a deprecation warning when running with docker_compose enabled:

[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: ['{{
 _docker_additional_packages_pip }}']` and remove the loop. This feature will be removed in version 2.11. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.

Thanks for reporting the deprecation warning. I try to keep this role compatible with the lowest supported Ansible version which is 2.5 right now so I keep track on this page when they drop support. https://docs.ansible.com/ansible/latest/reference_appendices/release_and_maintenance.html#release-status

Cheers!
