CLOUDP-278384: Support Independent ID config generation

[josvazg]

Proposed changes

Support a new flag for Kubernetes config generation so that resources that support independent usage are exporting with external ID references, instead of Kubernetes name references. In version 2.5 that means Atlas Database Users and Deployments will be exported with external project IDs when using the --independentResource flag like this:

$ atlas kubernetes config generate --projectId=<projectId> --independentResources

Users should extract the parts of the generated YAAMl definition that make sense for their use case.

I'm missing a dedicated independent CRD e2e test.
