[PIG-1459] Need a standard way to communicate the requested fields between front and back end for loaders

Description

Pig currently provides no mechanism for loader writers to communicate which fields have been requested between the front and back end. Since any loader that accepts pushed projections has to deal with this issue it would make sense for Pig to provide a standard mechanism for it.
