Suspends the given route using {@link org.apache.camel.spi.ShutdownStrategy}.
Suspending a route is more gently than stopping, as the route consumers will be suspended (if they support) otherwise the consumers will be stopped.
By suspending the route services will be kept running (if possible) and therefore its faster to resume the route.
If the route does
not support suspension the route will be stopped instead
@param routeId the route id
@throws Exception is thrown if the route could not be suspended for whatever reason
