[runwhen-local-feedback] Global Configuration Override for CodeBundle

[stewartshea]

Observation
There are times where a common codebundle, such as k8s-namespace-health, might want to have a global configuration override for a user. While we could fork this and modify the templates, I suspect it would be useful to have a configuration option inside of workspaceInfo.yaml for this as well.

Possible Suggestions
On a best-effort basis, we could take in some sort of path under the codecollections spec that enumerate the configuration override in a similar format as a kustomization patch.

Any other details or context
This simply makes it easier to apply the config across many instances rather than overriding each single one. We would still support per-slx overrides (which are handled at the RunWhen Platform configuration side). This option is just a way to override for all instances of a codebundle.
