Changes proposed in this PR

This PR allows for components to ship default YAML files which zwe will incorporate into the overall yaml config for when that particular component loads. Components need no code changes to take advantage of this. They will still receive env vars to use. However, they will now have env vars that consider values from their own defaults.yaml file, and will also have a merged yaml file available to them in workspace/.env/componentname

The purpose of this is to:

• reduce configuration values the user needs to see by default
• Allow servers to take configuration out of code and put it into yaml templates
• Allow users to see those defaults from those yamls, and then be better equipped to build their own yaml customizations.
