The YamlObject class was designed to represent data parsed from YAML files. It is outgrowing the initial needs. Move it to a separate file to prepare for a rename. Most files that include yaml_parser.h only need access to a YamlObject. Switch them to yaml_object.h. pipeline_base.cpp was including yaml_parser.h indirectly through pipeline_base.h, include it directly now.
