Subject: [PATCH] feat: Adopt existing K8s resources as Helm release on install
 (#746)

Use with the helm-x support(#673)

This enhances config syntax to accept adopt: [NS/KIND/RESOURCE_NAME] at the release level so that helmfile calls helm-x to transparently import existing resources at the installation time.

Resolves #84
