// FetchConfig reads the specified file from the SourceRepository and loads the

//
// The path must be in the format SOURCE_NAME/FILE/PATH.yml. The SOURCE_NAME
// will be used to determine the ArtifactSource in the SourceRepository to
// stream the file out of.
//
// If the source name is missing (i.e. if the path is just "foo.yml"),
// UnspecifiedArtifactSourceError is returned.
//
// If the specified source name cannot be found, UnknownArtifactSourceError is
// returned.
//
// If the task config file is not found, or is invalid YAML, or is an invalid
// task configuration, the respective errors will be bubbled up.
