Due to an ununsual interface to OS::Neutron::Port resources,
it's necessary to specify replacement_policy: AUTO, or the
resource is unconditionally replaced on every stack update.
I've started discussion re possibly changing the default in
Heat, but right now, we need this or we have the bad outcome
of replacing all (!) compute and controller nodes on every
stack-update, even if the templates are unmodified.
Passing the AUTO value should be safe regardless of any
potential change of default value in Heat.

This provides three templates: overcloud-without-mergepy.yaml,
compute.yaml and controller.yaml. These can be used in combination with
overcloud-resource-registry.yaml to deploy the overcloud on their own --
without having to do any pre-processing (via merge.py).
To test these you have to add the resource registry environment (in
addition to the existing `-e` option) and use the new overcloud template
in the Heat call in devtest_overcloud.sh (line 374):
heat $HEAT_OP -e $TRIPLEO_ROOT/overcloud-env.json \
-e "$TRIPLEO_ROOT/tripleo-heat-templates/overcloud-resource-registry.yaml" \
-t 360 \
-f $TRIPLEO_ROOT/tripleo-heat-templates/overcloud-without-mergepy.yaml \
-P "ExtraConfig=${OVERCLOUD_EXTRA_CONFIG}" \
$STACKNAME
The existing overcloud Heat environment
($TRIPLE_ROOT/overcloud-env.json) should keep on working. Scaling is
now being controlled by the `ControllerCount` and `ComputeCount`
template parameters, though.
NOTE: the changes here depend on a fairly recent Heat build (commit
e5f285f6cb from ~7th September, 2014). In other words, this requires
Juno Heat.
Also, passing more than one environment file to Heat requires
python-heatclient version 0.2.11.
