Refactor stack command/package
- Handle `bundlefile` directly in the `top-level`
  command. `bundlefile` is still experimental and will be deprecated
  in future version — this should make be easier to remove it.
- Validate the `stack` name in all cases (i.e. whatever the
  orchestrator is used)
- Load the composefile ahead of choosing the orchestrator. This
  removes some slight duplication.
- Makes `RunDeploy` easier to use from outside packages (like
  `docker/app`) with a preloaded configuration.
