Don't double restart glance-* services.

The init-openstack script restarts glance services that are also
restarted by the glance elements os-refresh-config hooks. We don't
manipulate glance in-image now, so we can just wait for them to
restart post-configure.

Don't double-restart nova-api.

Similar to glance, we used to poke at nova during in-instance setup
but that has been moved to API scripts from the deployer now, so we
don't need to force service availability before the rest of
os-refresh-config runs.

Drop heat-localip.

We only needed heat-localip to work around a race condition in our
heat templates. Those templates are now fixed, so there is no need to
have heat-localip at all.
