…g-ex input (#2810) * Bugfix to guard against stack overflow errors caused by very large reg-ex input This change fixes a code path that did not properly impose the index-level max_regex_length limit. Therefore, it was possibly to provide ar arbitrarily large string as the include/exclude reg-ex value under search aggregations. This exposed the underlying node to crashes from a StackOverflowError, due to how the Lucene RegExp class processes strings using stack frames.
