/**
 * A sibling pipeline aggregation which calculates the sum across all bucket
 * of a specified metric in a sibling aggregation. The specified metric must
 * be numeric and the sibling aggregation must be a multi-bucket aggregation.

 * @param {string} name The name which will be used to refer to this aggregation.

 *
 * @example
 * const reqBody = esb.requestBodySearch()
 *     .agg(
