// Package config defines the data models for entities. This file defines the
// models for configuration format. The defined entities are:
// Config (the top-level structure), Receivers, Exporters, Processors, Pipelines.
//
// Receivers, Exporters and Processors typically have common configuration settings, however
// sometimes specific implementations will have extra configuration settings.
// This requires the configuration data for these entities to be polymorphic.
//
// To satisfy these requirements we declare interfaces Receiver, Exporter, Processor,
// which define the behavior. We also provide helper structs ReceiverSettings, ExporterSettings,
// ProcessorSettings, which define the common settings and un-marshaling from config files.
//
// Specific Receivers/Exporters/Processors are expected to at the minimum implement the
// corresponding interface and if they have additional settings they must also extend
// the corresponding common settings struct (the easiest approach is to embed the common struct).
