In change I78cb60168aaa40bb6439198283546b7faf33917c, action was changed
to kolla_action, and serial to kolla_serial, to avoid Ansible warnings
due to use of reserved keywords. In that change, some keywords were
missed, and some changes that were merged since then have not switched
to the new variables. This change fixes all current instances of those
issues.
