CLOUDSTACK-8901: PrepareTemplate job thread hard-coded to max 8 threads The thread pool was hardcoded to use 8 threads,
com.cloud.template.TemplateManagerImpl.configure(String, Map<String, Object>):
_preloadExecutor = Executors.newFixedThreadPool(8, new NamedThreadFactory("Template-Preloader"));

Added the change to pick threadpool size from configuration.
