Fix fact tags

Ansible playbook fails when tags are limited to "facts,etcd" or to
"facts". This patch allows to run ansible-playbook to gather facts only
that don't require calico/flannel/weave components to be verified. This
allows to run ansible with 'facts,bootstrap-os' or just 'facts' to
gether facts that don't require specific components.
