// ReleaseService is the service that a helm application uses to mutate,
// query, and manage releases.
//
//		Release: A named installation composed of a chart and
// 				 config. At any given time a release has one
//				 chart and one config.
//
//		Config:  A config is a TOML file that supplies values
//				 to the parametrizable templates of a chart.
//
//		Chart:   A chart is a helm package that contains
//				 metadata, a default config, zero or more
//				 optionally parameterizable templates, and
//				 zero or more charts (dependencies).
