cli/command/image: pushTrustedReference: internalize constructing indexInfo

All information needed can be deducted from the image reference, which
is used to create a indexInfo, repoInfo, and to resolve auth-config.

In some situations this may result in resolving the auth-config twice
after it already was resolved to an encoded auth-config.
