 * This decorator is used to mark a method as an init method.
 * Init methods are called after the instance is created and all the decorators are processed
 * Takes an optional cleanup function as a parameter.
 * The cleanup function will be called when the instance is disposed by the disposal of the parent dependency container.
 *```ts
 * \@onInit
 *public init(cleanup: Cleanup) {
 *  const abortController = new AbortController()
 *  cleanup(() => {
 *    abortController.abort()
 *  })
 *
 *  const response = await loadData(this.state.id, abortController.signal);
 *  // do something
 *}
