[jvleminc]

If a user mentioned in the list list_of_os_users doesn't exist in the destination server for task 5.4.1.1, the task should not abort but simply continue with other users:

- name: 5.4.1.1 Ensure password expiration is 365 days or less\
    5.4.1.2 Ensure minimum days between password changes is configured\n
    5.4.1.3 Ensure password expiration warning days is 7 or more"
