Same as std::for_each, but which yields periodically. Written in a style which keeps in inner loop fast, equivalent to the non-async version (optimizer willing, but seems to be true in the case I checked). For the simplest use cases we offer async_for_each, which is the same as std::for_each except that it yields every Traits::Interval iterations: every call starts the "work counter" anew. For more complicated cases, like nested loops, it may be convenient to carry the counter from one iteration to the next, in order to yield at the correct times. For example, in a doubly nested loop where the inner loop always ran for less than Interval iterations, we would not yield with the simple functions. Issue redpanda-data/core-internal#1061.
