Implement an Exitable DirectoryReader that wraps the original DirectoryReader so that when a search task is cancelled the DirectoryReaders also stop their work fast. This is usuful for expensive operations like wilcard/prefix queries where the DirectoryReaders can spend lots of time and consume resources, as previously their work wouldn't stop even though the original search task was cancelled (e.g. because of timeout or dropped client connection).
