The container name needs to be passed with the stack name value to the
update_nodes workflow so that the right config container is used during
the update.
Previously, this was not an issue since all update actions just
defaulted to overcloud-config even if the stack name wasn't overcloud.
However, with the multiple overclouds feature and the multi-stack
feature, we need to make sure the right config container is used that
matches the stack name.
