Revert "Allow setting any_errors_fatal true for gather-facts"

This reverts commit 5b431f0f.

Reason for revert: the any_errors_fatal play parameter is not templated
by Ansible (tested up to ansible-core 2.15.9). This behaviour is
demonstrated in [1].

This means that "{{ kolla_ansible_setup_any_errors_fatal }}" is always
interpreted as 'true', regardless of the value of
kolla_ansible_setup_any_errors_fatal.  This is particularly bad because
the default value of kolla_ansible_setup_any_errors_fatal is false.

We now have gather_facts_max_fail_percentage which can be set to 0 to
provide the same functionality.
