Delivers upgrade scripts where upgrade steps are disabled

This delivers a /root/tripleo_upgrade_node.sh to those nodes
that have the disable_upgrade_deployment flag set to true.
They will later be upgraded manually by the operator who will
invoke the script delivered here using upgrade-non-controller.sh

We can also deliver any service specific upgrade configuration,
such as configuring nova-compute to use the placement API as this
is required in order for placement to be configured and installed
during the subsequent upgrade steps for controller services.

This removes the compute and swift specific upgrade scripts as
they are now merged into the common
tripleo_upgrade_node.sh - removing any hard coded
reference to a particular role name (compute/objectstorage) and
only relying on the disable_upgrade_deployment is roles_data.yaml
