Docker image missing some configuration

The artifactory image posted on bintray is missing a couple of things. First the docker-prod-local2 repo doesn't exist. It's present in nginx though.

Second there's no support for remote docker. That needs to exist in both nginx and artifactory.

Third the configuration is coming from an import .xml file. It should just be a regular configuration file so there's no risk of blowing away people's data.

Forth it would be nice to have support for jfrog-docker-registry.bintray.io/artifactory/artifactory-pro as a remote registry
