playbooks: bootstrap in facts playbook (#10069)

Calling bootstrap in facts.yaml so that we can always collect facts even on
new nodes. This is useful when you want to add nodes to an inventory
beforehand and then collect facts and scale the cluster with the scale
playbook and --limits. With dynamic inventory sometimes it might be more
difficult to add the nodes after running the facts playbook in this
specific situation.
