方法名：concatMapMaybeDelayError

Flowable.concatMapMaybeDelayError介绍

[英]Maps the upstream items into MaybeSources and subscribes to them one after the other terminates, emits their success value if available and delaying all errors till both this Flowable and all inner MaybeSources terminate.

Backpressure: The operator expects the upstream to support backpressure and honors the backpressure from downstream. If this Flowable violates the rule, the operator will signal a MissingBackpressureException. Scheduler: concatMapMaybeDelayError does not operate by default on a particular Scheduler.
[中]将上游项目映射到MaybeSources中，并在另一个终止后一个接一个地订阅它们，如果可用，则发出它们的成功值，并延迟所有错误，直到此可流动和所有内部MaybeSources终止。
背压：操作员希望上游支持背压，并尊重下游的背压。如果该流体违反规则，操作员将发出缺少背压异常的信号。调度程序：默认情况下，concatMapMaybeDelayError不会在特定调度程序上运行。
