HPCC-12093 'modified orphaned process cleanup to be component safe and allow for thorslave cleanup, the thorslave_lcr process is now symlinked to thorslave_<compName> under /var/lib/HPCCSystems/<compname> so we can easily do a killall for orphaned slaves.  Added cleanup_component to stop_component which will ensure orphans get cleaned up on start/stop/restart'
