Without this change the "Import variables specific to distribution"
tasks fail with "Could not find file on the Ansible Controller..."
on environments with inject facts disabled.
This changes the tests to run with ansible with
inject_facts_as_vars = false and fixes other roles and playbooks.
Bool types are not iterable. Therefore the comparison using sets was failing
with a TypeError. This prevented to change the bool parameters for hosts.
A test for the host module has been added to verify that the bool parameters
can be modified.
New test:
tests/host/test_host_bool_params.yml
