That's not how you want to go about customizing your deployment.

Rather than altering the original files, or the defaults, you want to
set parameters or defaults in environment files.

So, create an environment file with three sections:

resource_registry:

parameters:

parameter_defaults:

In these sections, you can override settings that appear in
overcloud.yaml and overcloud-resource-registry-puppet.yaml (in the
T-H-T root).

You include your environment file on the deployment command line with
-e <file>.

To help you with a basic understanding of how parameters are set:

overcloud-resource-registry-puppet.yaml is the source for where the
various resource files are found. These are occasionally overridden
when you want specific features enabled, such as when using network
isolation and you specify your NIC config YAMLs.

overcloud.yaml (in the T-H-T root) is where the parameters are all set.
If you want to override these, add the needed parameters to the
parameter_defaults: section. Sometimes it is necessary to put
parameters into the parameters: section (overriding their definition),
but usually adding parameter_defaults for the parameter is sufficient.

For examples, look in the environments directory inside
/usr/share/tripleo-heat-templates.
