 * Invokes a callback periodically until it successfully returns the result. If a callback throws an error or returns
 * a promise that is rejected then it is invoked again after a delay.
 *
 * @param cb The callback that must return the fulfilled result.
 * @param ms The number of milliseconds between the rejection of the last promise returned by the callback and the next
 * invocation. Or a callback that receives the latest error and returns the delay. If omitted then delay is 0.
 * @param maxCount The maximum number of retries after which the last rejection reason is thrown.
 * @template T The value returned by the callback.
 * @returns The promise that is fulfilled with the callback result.
