How to emulate spring import feature with Blueprint ?

Issue

• Pre conversion to OSGi user had two jar files that use Camel and Spring, lets call them the container jar and the adapter jar.
• Each one had resource directories with Spring XML files defining beans and the packages with the bean classes.
• The idea is that that camel-context is in the adapter jar and pulls in bean definitions from both the adapter jar and the container jar.
• Conversion to OSGI using Spring resolved all the XMLs files by using <import> to pull in the files on the imported packages. It worked, although very messy and not using any of the OSGi capabilities, like services.
