X-Forwarded-* aware UriInfo.getBaseBuilder

As far as I can see, UriInfo.getBaseBuilder() does not return a builder that is aware of headers like X-Forwarded-For or X-Forwarded-Proto.
It would be great to be able to control this. It seems that the UriBuilder is created is container-specific - for instance, here it is created in a servlet context: [https://github.com/jersey/jersey/blob/master/containers/jersey-servlet-core/src/main/java/org/glassfish/jersey/servlet/ServletContainer.java#L518](https://github.com/jersey/jersey/blob/master/containers/jersey-servlet-core/src/main/java/org/glassfish/jersey/servlet/ServletContainer.java#L518) The headers are still the same in any context, though.

The benefit here is that this will prevent developers from having to manually handle this in their resources, making both developing and deploying Jersey applications easier.
