Simon Willnauer 0cc0fd2d15 Add a frozen engine implementation (#34357) ... This change adds a `frozen` engine that allows lazily open a directory reader on a read-only shard. The engine wraps general purpose searchers in a LazyDirectoryReader that also allows to release and reset the underlying index readers after any and before secondary search phases.
