> Previous {{ParseFooUpdateProcessorFactory}}-s (see SOLR-4892) in the same chain will
detect, parse and convert unknown fields’ {{String}}-typed values to the appropriate Java
object type.
> This factory will take as configuration a set of mappings from Java object type to schema
field type.
> {{ManagedIndexSchema.addFields()}} adds new fields to the schema.
> If schema addition fails for any field, addition is re-attempted only for those that
don’t match any schema field.  This process is repeated, either until all new fields are
successfully added, or until there are no new fields (because the fields that were new when
this update chain started its work were subsequently added by a different update request,
possibly on a different node).
