Provide support for camel-spring from blueprint-spring

With the old spring-dm, there's a "BundleContextAware" interface, any bean implements this interface can get BundleContext injected.
With the new aries-blueprint-spring, we should follow similar pattern, like check if a bean has setBundleContext method, if so, just inject the BundleContext into the bean, so that the application bundles with work with spring-dm can also work with aries-blueprint-spring
