    Optimize container_cli usage by mysql-open-files-limit validation

    mysql-open-files-limit could fail because Ansible fails to obtain
    container_cli definition from inventory.

    There are multiple playbooks that use container_cli to run
    various commands. All playbooks but mysql-open-files-limit define
    container_cli in different way. This patch aligns container_cli
    definition and usage for mysql-open-files-limit validation with
    other validations.
