Move deprecated SchedulerHints logic to overcloud.j2.yaml

The changes in puppet/role.role.j2.yaml should have been made
to overcloud.j2.yaml, because we don't want the hard-coded reference
to the deprecated name in the parent template.  Note we need to
pass this value from the parent template so the %index% substitution
works, which is required for predictable placement via *SchedulerHints
