Convert UpdateWorkflow to support composable roles

We need to remove the hard-coded roles from overcloud.j2.yaml
as now it's valid to e.g remove BlockStorage completely.

The previous behavior for the per-role upgrade scripts is maintained
but we'll need to rework this for newton->ocata upgrades where we
can no longer be sure the servers mapping will contain all roles.
