Fix etcd-upgrade sanity checks
Fix etcd-upgrade sanity checks

This commit ensures that only oo_etcd_to_config and
oo_masters_to_config are checked during sanity_checks.

This will prevent hosts that have not had facts gathered
(such as nodes) will not be processed for correct inventory
and runtime facts.
