Enable v2 default push

When pushing to the official registry, v2 push will be attempted first. If the v2 endpoint is unavailable, a push to v1 will occur. If a v2 push is started and failed, the push operation will fail. Pulling non-official images the official v2 registry is also enabled to pull the newly push images. When a pull of a v2 image fails, v1 will always be attempted.
