According to Ansible we can use yes, true, True, "or any quoted st-
ring" for a boolean true, but ansible-lint wants us to use either
true or false.
See: https://chronicler.tech/red-hat-ansible-yes-no-and/
ansible-lint told me not to test equality with booleans using literal
"True" and "False", but it Ansible complains if I use "is True" also.
It seems that I need to adjust the syntax slightly.
Because of the shift from static imports to dynamic includes these
tags will never be reached unless they have their own task that is
tagged at the top-level (dynamic includes don't pass their tags to
their children).
