     * Gets the {@link Jenkins} singleton.
     * {@link #get} is what you normally want.
     * <p>In certain rare cases you may have code that is intended to run before Jenkins starts or while Jenkins is being shut down.
     * For those rare cases use this method.
     * <p>In other cases you may have code that might end up running on a remote JVM and not on the Jenkins controller or built-in node.
     * For those cases you really should rewrite your code so that when the {@link Callable} is sent over the remoting channel
     * it can do whatever it needs without ever referring to {@link Jenkins};
     * for example, gather any information you need on the controller side before constructing the callable.
     * If you must do a runtime check whether you are in the controller or agent, use {@link JenkinsJVM} rather than this method,
     * as merely loading the {@link Jenkins} class file into an agent JVM can cause linkage errors under some conditions.
     * @return The instance. Null if the {@link Jenkins} service has not been started, or was already shut down,
     *         or we are running on an unrelated JVM, typically an agent.
