test: ensure role gathers the facts it uses by having test clear_facts before include_role
The role gathers the facts it uses. For example, if the user uses `ANSIBLE_GATHERING=explicit`, the role uses the `setup` module with the facts and subsets it requires. This change allows us to test this. Before every role invocation, the test will use `meta: clear_facts` so that the role starts with no facts. Create a task file tests/tasks/run_role_with_clear_facts.yml to do the tasks to clear the facts and run the role. Note that this means we don't need to use `gather_facts` for the tests. Some vars defined using `ansible_facts` have been changed to be defined with `set_fact` instead. This is because of the fact that `vars` are lazily evaluated - the var might be referenced when the facts have been cleared, and will issue an error like `ansible_facts["distribution"] is undefined`. This is typically done for blocks that have a `when` condition that uses `ansible_facts` and the block has a role invocation using run_role_with_clear_facts.yml These have been rewritten to define the `when` condition using `set_fact`. This is because the `when` condition is evaluated every time a task is invoked in the block, and if the facts are cleared, this will raise an undefined variable error.
