Issues addressed:
- Remote API doco refers to "registry" parameter which is not supported
- Neglects to mention "tag" parameter which is supported
- Offers no guidance on pushing to private registries
Changes made:
- As directed in review comments, `registry` removed from all api versions (1.0-1.14)
- Have added documentation for `tag` parameter and guidance on private registries for versions 1.10-1.14 (I have only validated this on .10)
