Block upstream models from triggering

[ddumas100]

I want to guarantee exclusion of certain "special" models from "triggering" downstream models from running in jobs. I use tags and use --exclude tag:
That works fine.
However, I feel this below is a more robust solution. At the top of a model, a new config setting could guard models with upstream refererences to it from running:
-- this model is dim_customers. I want to prevent models that ref() this model below from triggering (solely because it's used in an upstream ref)
{{
config(ignore_upstream_ref = "true")
}}
A scenario for this is conformed dimensions, that get ref()'d all over the place. This triggers undesired model builds. The above would prevent that.
