David Roberts 2ca1ddf017 [ML] Tell native controller process to stop during graceful shutdown (elastic/x-pack-elasticsearch#644)
Fixes elastic/prelert-legacy#803

On Windows the JVM hangs during shutdown if the native controller process
is still running. A thread dump suggests this is because of a finalizer being
blocked. We can avoid the problem by explicitly telling the controller to exit
when the node is stopped. Although the hang is Windows-specific, it doesn't
hurt to do this on *nix too.
