The get-indices API does some nontrivial work on the master and at high index counts the response may be very large and could take a long time to compute. Some clients will time out and retry if it takes too long. Today this API is not properly cancellable which leads to a good deal of wasted work in this situation, and the potentially-enormous response is serialized on a transport worker thread. With this commit we make the API cancellable and move the serialization to a `MANAGEMENT` thread. Backport of elastic#87681 Relates elastic#77466
