Allow combining yamls from different sources, blacklisting resources and overriding replicas

[druppelt]

My goal is to import the resource descriptions from a running cluster, optionally adjust the replicas, deselect some, add the local resources, to then calculate how much quota I would need for all that together.
The usecase would be a namespace representing the dev or staging environment, which uses lower replicas than prod and also has applications that are only needed in dev. Now I want to add my new not yet deployed application and already calculate how much quota I will need in prod.

Currently i can get the resources with kubectl or oc, manually edit the replicas and concat that with my local resources and pipe that into the CLI.

I would like some kind of workflow improvement. Still very much in ideation phase.
